Siemens FI circuit breaker type AC short time delayed A 30 mA Un

FI circuit breaker, 4-pole, type AC, short-time delayed, In: 40 A, 30 mA, Un AC: 400 V, can be pre-protected against overload with rated current. The FI switch is the residual current protective device for touch protection. Siemens' patented residual current devices are an important part of the SENTRON protection components 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 the start. Whether through direct contact with live parts or indirect contact with operating equipment, protection is primarily achieved through rapid disconnection. Siemens FI circuit breakers 5SV are characterized by: comprehensive protection for people and property against electric shock. Whether sinusoidal alternating fault currents or smooth direct fault currents - Siemens offers the right solution for all requirements.
