The motor-protection designation means the ETU350M includes phase-failure detection, so a lost phase on a motor feeder trips the breaker rather than letting the motor single-phase and burn. The trip indicator on the front gives a clear visual when the breaker has opened on fault — no guessing whether it was a manual off or a trip event. ## Thermal derating and the real-world current limit At 55 °C it derates to 96 A, at 60 °C to 94 A, and at 65 °C to 92 A, with a floor of 90 A at 70 °C. The maximum power loss is 75 W, which factors into the enclosure thermal calculation. ## Auxiliary contacts and wiring That gives you two form-C contacts for status feedback (open/closed) and a separate alarm contact that changes state only on a trip event — not on manual switching. The auxiliary release slot is empty (no shunt or undervoltage release fitted), so if you need remote tripping, that has to be added as a field-installable accessory.","metaTitle":"Siemens 3VA2110-5MN32-0AH0 SENTRON MCCB, 100 A, 187 kA","metaDescription":"Siemens SENTRON 3VA2110-5MN32-0AH0 molded case circuit breaker, 100 A rated, 187 kA at 240 V, ETU350M trip unit, motor protection, 3-pole.
