⚡ Key Features

Protects circuits at 25 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.
4 Poles — protects a three-phase four-wire circuit with switched 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 CB90004OODO 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 CB90004OODO protect at its rated 25 A?

A: The CB90004OODO is rated to carry and protect circuits up to 25 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 25 A rating is used directly. Derate by 20% for ambient temperatures above 40°C.

Q: What does the 6 kA breaking capacity on the CB90004OODO mean in practice?

A: Breaking capacity (6 kA) is the maximum prospective short-circuit current the CB90004OODO 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 CB90004OODO and what loads is it optimised for?

A: Curve C on the CB90004OODO 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: Why is the 100 mA sensitivity specified on the CB90004OODO and when should you choose a different rating?

A: 100 mA is the residual current at which the CB90004OODO will trip within 300ms. A 30mA sensitivity provides additional shock protection (mandatory for socket circuits per IS 732). 100mA is used for fire protection (no shock protection). 300mA protects feeders without nuisance tripping. Choose based on the circuit’s risk profile — never use >30mA for socket outlet circuits in wet or high-risk locations.

Q: Can the CB90004OODO be DIN rail mounted in any standard distribution board?

A: Yes. This CB90004OODO 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.
