The interrupting capacity follows a steep voltage curve: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. Above that it steps down: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. The physical footprint is 70 mm deep by 76.2 mm wide by 130 mm tall, which fits the standard SENTRON 3VA mounting footprint; no extra DIN-rail adapter needed. ## Auxiliary contacts and shunt trip That gives you one N/O + one N/C auxiliary mirroring the main contacts, and a separate alarm contact that changes state only when the breaker trips on fault — useful for remote fault annunciation without wiring through the aux contacts. The integrated shunt trip (STL) release is order code 3VA9688-0BL33; it is a voltage-trigger accessory that lets a remote signal (PLC digital out, emergency-stop relay) force the breaker open.","metaTitle":"Siemens 3VA1132-3EF32-0KH0 SENTRON MCCB, 32 A, 3-Pole, 70 mm","metaDescription":"Siemens 3VA1132-3EF32-0KH0 SENTRON molded case circuit breaker, 32 A rated, 3-pole, TM240 release, 75.6 kA at 240 V.
