It's a line-protection device — meaning it's configured to protect cables and busbars from overload and short-circuit, not motor or generator circuits. The interrupting ratings climb to 75.6 kA at 240 V and 52.5 kA at 415 V, which gives you headroom for high-fault utility feeds or transformer secondaries in industrial distribution panels. The 32 A rating holds flat from 40 °C through 50 °C, then derates gradually to 28.8 A at 70 °C — so in a warm panel you lose about 10% of capacity at the top end. That's typical for a thermal-magnetic breaker; the bimetal element responds to ambient heat. That means you can remotely trip the breaker from an E-stop or safety relay without adding an external undervoltage module. This is a clean, basic line-protection MCCB with a shunt trip for remote opening. Mounting is screw-clamp or plug-in onto a busbar system; the SENTRON 3VA range uses a common base and accessory system. The shunt trip wiring connects to the breaker's internal terminals — verify polarity if the release is DC-powered, though the spec does not detail coil voltage here. The auxiliary trip order code 3VA9688-0BL33 is a separate accessory that mounts on the breaker side; it provides a signal contact for remote status indication.","metaTitle":"Siemens 3VA1132-3EF32-0KA0 SENTRON MCCB, 32 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1132-3EF32-0KA0 molded case circuit breaker, 32 A rated, 3-pole, 75.6 kA at 240 V.
