The Siemens SENTRON 3VA1110-6EF36-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current at 40 °C, with a TM240 thermal-magnetic overcurrent release. The interrupting ratings are what make this part stand out: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. The 70 mm depth and 76.2 mm width match the standard SENTRON 3VA mounting footprint, so it drops into existing panel layouts that already use 3VA breakers.
At 55 °C it's 96 A, at 60 °C it's 94 A, at 65 °C it's 92 A, and at 70 °C it's 90 A. That's a gentle slope; you don't lose much headroom even in a hot enclosure. It's a straightforward, reliable overcurrent trip for applications where you don't need selectivity curves or remote signaling. The shunt trip (STL) is built in, so you can remotely open the breaker via a control signal; the auxiliary trip accessory is order code 3VA9688-0BL32 if you need that later. No undervoltage release, no auxiliary contacts, no phase-failure detection — this is a bare-bones line-protection breaker with a high interrupt rating and a shunt trip.
