⚡ Key Features

Protects circuits at 10 A with 6 kA short-circuit breaking capacity — rated for residential and commercial final circuits.
Curve B tripping characteristic — optimised for cable and resistive loads (lighting, heating, socket circuits) — trips magnetically at 3–5× rated current.
1 Pole — protects a single-phase final circuit; fits standard 35mm DIN rail in distribution boards.
Thermal-magnetic trip mechanism — bimetal element trips on sustained overload, instantaneous magnetic trip on short-circuit; two independent protection functions in one compact module.
Manufactured to IS 8828 / IEC 60898-1 (residential) and IEC 60947-2 (industrial) — complies with the applicable Indian BIS and IEC international standards for this product category.
BIS certified where applicable — meets Indian regulatory requirements for use in government, commercial, and industrial electrical installations.
Genuine authorised BA10100B product — sourced directly from the official distribution network with full manufacturer traceability and warranty.
GST invoice provided for India orders — valid for corporate procurement, government project orders, and public tender supply via myelectric.in.
Worldwide export available — UAE, Singapore, UK, USA, Sri Lanka & more. Contact +91 94814 00316 for bulk pricing and international shipping.

❓ Frequently Asked Questions

Q: What load can the BA10100B protect at its rated 10 A?

A: The BA10100B is rated to carry and protect circuits up to 10 A continuously. For motor loads, ensure the full-load current (FLC) of the motor does not exceed this rating. For resistive loads (heaters, lighting), the 10 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 6 kA breaking capacity on the BA10100B mean in practice?

A: Breaking capacity (6 kA) is the maximum prospective short-circuit current the BA10100B can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 6 kA — this is checked using a fault level calculation or from the upstream transformer impedance data. Installing a breaker with insufficient breaking capacity is a serious safety violation.

Q: Why is Curve B specified for the BA10100B and what loads is it optimised for?

A: Curve B on the BA10100B trips magnetically at 3–5× rated current, making it ideal for resistive loads such as incandescent lighting, electric heaters, and PTC elements. Using the wrong curve can cause nuisance tripping (too sensitive) or inadequate protection (not sensitive enough). Always match the curve to the load’s inrush characteristics.

Q: What happens when the BA10100B trips — how do I identify and reset it?

A: When the BA10100B trips on fault, the handle moves to a midway position (between ON and OFF), distinctly visible from a distance. To reset: (1) identify and rectify the fault, (2) push the handle fully to OFF, (3) then switch back to ON. Never force-reset without investigating the fault cause.

Q: Is the BA10100B suitable for both single-phase and three-phase systems?

A: The BA10100B is a 1 pole device for single-phase circuits. For three-phase circuits, use a 3-pole or 4-pole MCB of the same series.
