That adjustability lets you fine-tune the trip curve to match the load — a 30A motor branch, for instance, can be set at Ir=30A and Ii=5xIn (150A) to ride through startup inrush without nuisance tripping. ## Shunt trip and accessories The breaker includes a shunt trip (STL) rated for 12-30V DC or 24V AC 50/60Hz, plus a nut keeper kit. The shunt trip allows remote tripping from an emergency stop or a PLC digital output — useful in a wastewater lift station where you want to kill power to a pump from the SCADA room without walking the panel.","metaTitle":"Siemens 3VA1140-4EF32-0HA0 Circuit Breaker, 36kA @ 415V, 40A","metaDescription":"Siemens 3VA1140-4EF32-0HA0 IEC frame 160 circuit breaker, 36kA breaking capacity at 415V, 3-pole, TM240 line protection, In=40A, shunt trip.
