Breaking capacity is the headline here: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and still 11.9 kA at 690 V. Current rating holds at 100 A up to 50 °C, then derates to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. If your panel ambient runs 55 °C, you lose 4 A of headroom — plan the load at 96 A maximum, not the nameplate 100. The UVR drops the breaker on loss of control voltage — common for emergency-stop circuits where a voltage-monitored shunt is required. ## Fit and integration — panel swap or new build The 3VA1110-4EF32-0CH0 is a fixed-format MCCB with no communication module (no PROFIBUS, no Modbus). It's a pure power distribution device — no phase-failure detection, no ground-fault monitoring. If you need those, you add external relays or step up to the 3VA9 accessories or a 3VA1 variant with the optional ground-fault module. The TM240 release is non-interchangeable — if you need a different trip curve or rating, you replace the breaker, not the trip unit. For DC networks, refer to the 3VA device manual for derating.","metaTitle":"Siemens 3VA1110-4EF32-0CH0 SENTRON MCCB, 100A, 121kA at 240V","metaDescription":"Siemens SENTRON 3VA1110-4EF32-0CH0 molded case circuit breaker, 100A rated, 121kA breaking at 240V.
