Siemens FIBlock type A selective A 300 mA Un AC

FI circuit breaker, 4-pole, Type A, selective, rated current: 40 A, residual current: 300 mA, AC voltage: 400 V. The FI switch is the residual current protective device for touch protection. Siemens' patented residual current protective devices are an essential component of the SENTRON protection devices for electrical installations, as they prevent life-threatening electrical accidents by safely disconnecting dangerous fault currents to ground. Electrically ignited fires can be prevented right from their inception. Whether through direct contact with live parts or indirect contact with operating equipment, protection is primarily achieved through rapid disconnection.
