⚡ Key Features

Protects circuits at 6 A with 6 kA short-circuit breaking capacity — rated for residential and commercial final circuits.
Curve C tripping characteristic — optimised for general-purpose and inductive loads (motors, mixed circuits) — trips magnetically at 5–10× rated current.
2 Poles — protects a single-phase circuit, switching both live and 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 L&T 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 BB2006DC protect at its rated 6 A?

A: The BB2006DC is rated to carry and protect circuits up to 6 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 6 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 6 kA breaking capacity on the BB2006DC mean in practice?

A: Breaking capacity (6 kA) is the maximum prospective short-circuit current the BB2006DC 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 C specified for the BB2006DC and what loads is it optimised for?

A: Curve C on the BB2006DC 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 BB2006DC suitable for both single-phase and three-phase systems?

A: The BB2006DC is a 2 poles device for single-phase circuits. For three-phase circuits, use a 3-pole or 4-pole MCB of the same series.

Q: Can the BB2006DC be DIN rail mounted in any standard distribution board?

A: Yes. This L&T 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.
