Application & Use-Case

A 16 A MCB is a good fit for residential or light-commercial circuits where the expected current might be up to 16 A—such as lighting clusters, fan banks, small AC units, or general purpose circuits requiring more capacity than 10 A.

The C‐curve means it will tolerate a moderate surge/inrush (such as from motors or fluorescent lights) but still provide effective overload/short-circuit protection.

Given brand and build quality (Anchor Roma), it’s suitable for modular distribution boards, and in environments like Chennai you’ll benefit from its reliability and form-factor.

What to Check / Installation Notes

Confirm the model number (for example “66153” series) and check it matches your specific circuit requirements.

Ensure your distribution board (MCB panel) supports mounting of the “Mini Modular” style MCB (check width/module count).

Verify that your wiring gauge, upstream protective device (breaker/MCB), and actual load are compatible with a 16 A rating.

Ensure proper mounting, secure terminals, correct earthing, and consider the ambient conditions (heat/humidity)—especially in coastal/humid areas like Chennai.

Make sure you buy from an authorised dealer to ensure authenticity, warranty and correct build quality.

Key Specifications & Features

Current rating: 25 A (single‑pole for example model “66155B”).

Tripping characteristic / curve type: “C”‑curve version (meaning it allows moderate inrush current before tripping, suited for general loads).

Poles: Available in Single‑Pole (SP) and Double‑Pole (DP) variants. For example SP model “66155B” and DP model “66161B”.

Breaking capacity: 3 kA (3000 A) short‑circuit breaking capacity noted in listings.

Rated voltage: ~240 V AC (single phase) for typical variant.

Material / build: Housing made of polycarbonate / moulded flame‑retardant plastic. For example one listing states “Material: Polycarbonate”.

Series / finish: Part of the Roma Urban / Roma Plus / Classic modular line — meaning modular mounting, aesthetic finishes, colour variants. Example: model “66155S” (silver finish).

---

Applications & Considerations

The 25 A rating makes this MCB appropriate for circuits drawing moderate current loads — heavier than the standard lighting/fan circuits (10–16 A) but not massive motor loads (which might need higher rated breakers or dedicated motor starters).

In a modular distribution board setup (in a home, office or hospitality installation), the mini modular format of the Roma series allows sleek mounting and integration with other modular devices (switches, sockets, etc).

If you install this in a coastal/humid area (like Chennai, Tamil Nadu), ensure proper wiring, good quality termination, and that the panel/enclosure protects against moisture and dust — the build quality is good, but environment still matters.

Ensure upstream wiring, cable size, protective devices, and load calculations are aligned with the 25 A rating (i.e., don’t just install a 25 A breaker if your wires are sized for 10 A).

Check model variant: some variants may have finish differences (white/black/silver) or number of poles; the datasheet and packaging should match your need.

What To Verify Before Purchase or Installation

Exact Part Number: e.g., SP variant “66155B”, DP variant “66161B” (or Roma Plus variant “89990”). Confirm you’re getting the correct one for your installation.

Tripping Curve: Confirm “C” curve is appropriate (for general use). If your circuit has high inrush (motors, compressors) maybe an “D” or motor‑rated breaker is needed.

Breaking Capacity: Make sure the 3 kA (or whatever spec) matches the available fault current for your installation.

Mounting / Module Width: Since this is a mini modular unit, check your distribution board has space and proper rail/slots for modular MCB mounting.

Finish and Aesthetics: If you’re matching with other modular devices from the Roma range (switches, sockets), pick colour/finish accordingly (white, black, silver).

Material / Standards: Ensure the housing is flame‑retardant plastic (with appropriate rating), the product carries IS/IEC compliance (e.g., IS/IEC 60898‑1) and brand authenticity.

Environment & Wiring: Ensure quality installation — good cable gauge, correct torque on terminals, proper earthing, good ventilation/protection from moisture.

Description
Rated current: 10 A.
Poles: Single‐pole (SP) version; there are also DP (double‑pole) variants.
Tripping characteristic: “C” curve — designed for general purpose circuits where moderate inrush may happen (such as lighting, small motors) rather than very high inrush.
Standard compliance: Matches standards like IS/IEC 60898‑1 for moulded case/micro breakers.
Series / Brand: Anchor by Panasonic Life Solutions India Pvt Ltd, under the Roma or UNO modular wiring‑accessories series. E.g., “Anchor Roma MCB SP 10A” listing.
Usage/Application: Provides protection for low current circuits against overloads and short‐circuit conditions in residential/commercial electrical installations. For example, one listing mentions “Applications: Residential, Commercial …” for the 10A SP MCB.
Modular design: The breaker is designed for modular panels/boards (“UNO Mini/Modular” type) making it suitable for modern distribution boards with DIN rail or modular panel mounting.
Materials/Housing: High quality, flame retardant plastic housing and mechanism for safe operation. For example listing mentions “Flame Retardant Material of Housing”.

Practical Use & Considerations
This 10 A breaker is good for protecting circuits that draw up to around 10 A (at rated voltage) — e.g., lighting circuits, smaller plug circuits, maybe fan banks, etc.
Since it uses a “C” curve tripping characteristic, it is somewhat tolerant of moderate inrush currents (for example when lights switch on or small motors start) compared to “B” curve, but still trips faster for higher fault currents compared to “D” curve.
For installation in a place like Chennai (coastal/humid environment), ensure proper enclosure (enough ventilation, no water ingress), correct wiring gauge, correct breaker mounting and that the breaker is installed as per manufacturer instructions and compliant electrical norms.
Make sure the upstream wiring, breaker panel, isolation and earthing all match the system expectation. A 10 A breaker is only as good as the circuit it protects; wiring must be appropriate for that rating.
Since it’s modular, if you are replacing or adding in an existing panel it should fit neatly, but you must check panel capacity, breaker footprint, DIN rail mounting and any code/labeling requirements.

What To Check / Before Purchase
Exact model number/variant: For example, listings show part numbers like 98070 (10A SP Mini MCB) for the Anchor Roma Classic/UNO.
Poles required: If you need neutral switching too or 2‐pole protection, choose DP variant rather than SP.
Breaking capacity / fault current rating: Ensure the MCB’s breaking capacity (e.g., 3 kA, 6 kA etc) meets the fault current at your location. The listing for the mini MCB mentions breaking capacity aspects in general.
Mounting and size compatibility: Modular size (UNO/mini), onto DIN rail or modular panel, clearance, labeling.
Certification & authenticity: Ensure genuine Anchor by Panasonic product, certified by BIS or relevant Indian standard, so reliability and warranty are in place.
Installation environment: Cable size, breaker rating matching, distribution board adequacy, ambient temperature and humidity, maintenance.
Load matching: If the circuit may draw more than 10 A or has large motors/heavy loads, you might need a higher rating (16A, 20A) rather than 10 A.

Key Specifications & Features
Rated current: 32 A (single‑pole or double‐pole depending on variant).
Characteristic curve: “C”‑curve, meaning standard general‑purpose circuit protection with moderate inrush tolerance.
Series / Model examples:
SP variant: model 66156B (32 A SP ‘C’ Mini Modular) in the Roma Urban line.
DP variant: model 66162B (32 A DP ‘C’ Mini Modular) in Roma Urban line.
Also listing: Ref. No. 98080 for 32 A DP in the Roma Classic/UNO range.
Rated voltage: ~ 240 V AC (single phase) or as applicable for the installation.
Short‐circuit breaking capacity: ~3 kA (3000 A) for many variants.
Housing / material: The case and cover are made of moulded flame‑retardant plastic (e.g., polycarbonate) and the range uses “mini modular” mounting (compact, snap‐fit style).
Finish & design: The “Roma Urban / Roma Classic” lines emphasise a sleek modern look with good surface finish and compatibility with modular plates. Examples: colour variants (black, silver), module size “1 M” etc.
---
Use‑cases & Considerations
Suitable for circuits that demand up to 32 A protection — e.g., heavier lighting/fan circuits, small air‐conditioner circuits, or general purpose power circuits in residential, commercial or light industrial settings.
Because it’s a modular mini MCB, it integrates into standard modular board/consumer‐unit installations (common in India).
Ensure that upstream wiring (cable size), circuit breaker panel and other protective elements are rated appropriately for a 32 A circuit — installing a 32 A MCB doesn’t automatically make the wiring safe unless it is rated accordingly.
For regions like Chennai (humid/coastal), good installation practice (ventilation, sealing, torque on terminals, corrosion prevention) enhances longevity and safety.
Have the correct variation: SP vs DP, colour/finish, module width, series (Roma Classic vs Roma Urban), etc.
