This is the version with a factory-integrated shunt trip (STL) release — the auxiliary trip module is the 3VA9688-0BL30. That means you can remotely trip the breaker via a control signal, which is standard for emergency-stop circuits or interlocking schemes. ## Thermal derating and real-world fit Above that, the breaker derates linearly: 612 A at 45 °C, 593 A at 50 °C, 575 A at 55 °C, 557 A at 60 °C, 538 A at 65 °C, and 520 A at 70 °C. That's a standard SENTRON 3VA2 frame footprint — it bolts into the same mounting pattern as other 3VA2 breakers in this current class. ## Trip unit and release details The ETU350 is an electronic overcurrent release with LSI protection curves (long-time, short-time, instantaneous). It's adjustable, which gives you coordination flexibility downstream. The shunt trip (STL) is a voltage-trigger release — apply rated control voltage and the breaker opens. The breaker does not include a trip indicator, auxiliary contacts, or ground-fault monitoring.","metaTitle":"Siemens 3VA2463-7HN32-0HA0 SENTRON MCCB, 630 A, 3-Pole, ETU3","metaDescription":"Siemens SENTRON 3VA2463-7HN32-0HA0 molded case circuit breaker. 630 A continuous, 3-pole, ETU350 electronic trip, 330 kA at 240 V.
