WHKB1L-40 (1P + N) Series Small Leakage Protection Device
WHKB1L-40 series leakage circuit breaker is suitable for lines with AC 50Hz, rated voltage 230V, rated current to 40A and below. It is used to protect people from indirect contact, and to protect buildings and similar lines from overcurrent. It can also protect the fire arch caused by the persistent ground fault due to the inaction of the overcurrent protection device.

WHKB1L-40 series leakage circuit breaker is suitable for lines with AC 50Hz, rated voltage 230V, rated current to 40A and below. It is used to protect people from indirect contact, and to protect buildings and similar lines from overcurrent. It can also protect the fire arch caused by the persistent ground fault due to the inaction of the overcurrent protection device. Leakage circuit breakers with overvoltage protection also protect against excessive voltage rises caused by power grid faults. This series of leakage circuit breakers has been increasingly used in low-voltage distribution systems as ground faults and direct contact and indirect contact electric shocks. Backup protection.
