IS 12640 (Part 2)
Electrical - Residual current operated circuit breakers for household and similar uses–Part 2 Circuit breakers with integral overcurrent protection(RCVOs)
Summary
Residual Current Operated Circuit Breakers with Integral Overcurrent Protection (RCBOs) are electrical safety devices that combine protection against earth leakage, overload, and short circuits in a single unit. They are commonly used in household and similar electrical installations to prevent electric shock and fire hazards.
Why BIS Certificate is Mandatory for Residual Current Operated Circuit Breakers With Integral Overcurrent Protection for Household & Similar Uses (RCBOs) ?
BIS certification is mandatory for RCBOs to ensure electrical safety, reliability, and compliance with Indian Standards. These devices protect human life from electric shock and fire risks. Mandatory certification prevents the sale of unsafe or substandard products in the Indian market.
What is BIS Certified for Residual Current Operated Circuit Breakers With Integral Overcurrent Protection for Household & Similar Uses (RCBOs) ?
RCBOs must comply with IS/IEC 61009-1, the Indian Standard specified by BIS. This standard defines requirements for design, performance, rated current, breaking capacity, leakage sensitivity, endurance, and safety tests, ensuring reliable protection in household and similar electrical installations.
