⚡ Key Features

Protects circuits at 1 A with 10 kA short-circuit breaking capacity — rated for light industrial and commercial distribution boards.
Curve C tripping characteristic — optimised for general-purpose and inductive loads (motors, mixed circuits) — trips magnetically at 5–10× rated current.
3 Poles — protects a three-phase circuit without neutral; 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 BB30010C 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.

❓ Frequently Asked Questions

Q: What load can the BB30010C protect at its rated 1 A?

A: The BB30010C is rated to carry and protect circuits up to 1 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 1 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 10 kA breaking capacity on the BB30010C mean in practice?

A: Breaking capacity (10 kA) is the maximum prospective short-circuit current the BB30010C can safely interrupt without damage. Before installing, verify that the prospective fault level at the installation point does not exceed 10 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 C specified for the BB30010C and what loads is it optimised for?

A: Curve C on the BB30010C trips magnetically at 5–10× rated current, making it ideal for general-purpose circuits including fluorescent lamps, small motors, and mixed loads. 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: Is the BB30010C suitable for both single-phase and three-phase systems?

A: The BB30010C with 3 Poles can protect three-phase circuits. Each pole simultaneously interrupts one phase — ensuring all phases are de-energised on a fault.

Q: Can the BB30010C be DIN rail mounted in any standard distribution board?

A: Yes. This BB30010C MCB uses the standard 35mm EN 60715 DIN rail and 17.5mm module width, making it compatible with all major brand distribution boards and enclosures. Terminal capacity accommodates both rigid and flexible conductors up to the rated cross-section.
