Siemens 5SY4 Circuit Breaker – 5SY46166

The Siemens 5SY4 installation circuit breaker features a slider mounting system. This allows the circuit breaker to be installed and removed from DIN rails without tools. The tighter magnetic trip curves of the Siemens circuit breaker ensure better selection of protections. Siemens 5SY4 circuit breakers are available in different variants.
