CQB91LE-40 6kA Residual Current Operated Circuit Breaker with Over-current Protection (Electronic)
Inquire NowDescription
The CQB91LE-40 Residual Current Operated Circuit Breaker is a vital safety device designed to provide protection against electric shocks and leakage currents in residential and commercial electrical systems. Suitable for AC 50Hz and rated for a single pole two lines configuration at 230V, this circuit breaker can handle a rated current of up to 40A. In the event of an electric shock or when leakage current exceeds established thresholds, the CQB91LE-40 swiftly disconnects the power supply to safeguard both human life and electrical equipment. With integrated overload and short circuit protection, it is adept at preventing damage to lines and motors. This breaker also serves as an infrequent conversion start for circuits under normal conditions, ensuring reliable operation and compliance with GB/T16917.1 and IEC61009-1 standards.
