Current rating holds at 160 A up to 50 °C ambient; above that it derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. That's typical for a distribution MCCB — not a switching-duty contactor, but fine for infrequent isolation and fault protection. ## Undervoltage release and auxiliary contacts That's a common requirement for safety circuits and emergency-stop chains where you want the breaker to drop out on loss of control power. No communication function, no phase failure detection, no ground fault monitoring, and no voltage trigger are fitted on this order code. If you need those, you're looking at a different 3VA variant with the electronic trip unit or the communication module. The integrated auxiliary trip is order code 3VA9608-0BB25 — that's the factory-fitted internal accessory for shunt or UVR wiring. If you're replacing this breaker in an existing panel, verify the auxiliary wiring matches your control scheme before pulling the old one.","metaTitle":"Siemens 3VA1116-4EF36-0DC0 SENTRON MCCB, 160 A, 3-Pole, 121","metaDescription":"Siemens SENTRON 3VA1116-4EF36-0DC0 molded case circuit breaker, 160 A rated current, 3-pole, 121 kA breaking capacity at 240 V.
