⚡ Key Features
- Protects circuits at 10 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 CB90005OOVO 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 CB90005OOVO protect at its rated 10 A?
A: The CB90005OOVO 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 CB90005OOVO mean in practice?
A: Breaking capacity (6 kA) is the maximum prospective short-circuit current the CB90005OOVO 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 CB90005OOVO and what loads is it optimised for?
A: Curve C on the CB90005OOVO 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 300 mA sensitivity specified on the CB90005OOVO and when should you choose a different rating?
A: 300 mA is the residual current at which the CB90005OOVO 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: What happens when the CB90005OOVO trips — how do I identify and reset it?
A: When the CB90005OOVO 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.
