That means in a warm panel you lose only 10 A at the top of the operating range, so the thermal margin is tight but usable for a 100 A bus. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V; at 690 V it still clears 10.5 kA. The TM240 thermal-magnetic release is fixed-trip, line-protection curve — no electronic adjustment, no communication module, no ground-fault or phase-failure detection. It does carry a shunt trip (STL) as the auxiliary release, ordered separately as 3VA9688-0BL30, and a voltage-trigger function for remote tripping. That depth is the body only — add clearance for the shunt-trip wiring and any finger-safe covers. The 15 000-cycle mechanical endurance is standard for a fixed-trip MCCB in a distribution panel — not a switching device for frequent motor starts, but fine for infrequent isolation and fault clearing.","metaTitle":"Siemens 3VA1110-3EF32-0HA0 SENTRON MCCB, 100 A, 3-pole, line","metaDescription":"Siemens 3VA1110-3EF32-0HA0 SENTRON molded case circuit breaker, 100 A rated continuous current, 3 poles, line protection.

The 3VA1110-3EF32-0HA0 uses a TM240 thermal-magnetic release with a shunt trip; the 5EE variant uses an electronic release. They share the same 100 A frame and three-pole layout, so physical interchange is possible, but the trip curve and auxiliary wiring differ — verify the release type against your coordination study before swapping."},{"question":"What are the key ratings for 3VA1110-3EF32-0HA0?","answer":"Rated continuous current Iu 100 A (derates above 50 °C to 90 A at 70 °C).
