Breaking capacity is the headline: 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. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — a standard 3-pole MCCB footprint that drops into a SENTRON panelboard or a DIN-rail adapter kit. At 55 °C it drops to 96 A, at 60 °C to 94 A, at 65 °C to 92 A, and at 70 °C to 90 A. If the breaker sits next to a heat source or in a sealed enclosure running hot, the 70 °C derated figure of 90 A is the number to use for the BOM. ## Auxiliary contacts and trip signaling That's enough for a remote status LED, a PLC digital input for fault annunciation, and a spare contact for a shunt-trip interlock. The integrated auxiliary trip is order code 3VA9688-0BL30 — a factory-fit accessory, not field-addable without pulling the breaker.","metaTitle":"Siemens 3VA1110-4EF32-0HH0 SENTRON MCCB, 100 A, 3-Pole, Line","metaDescription":"Siemens SENTRON 3VA1110-4EF32-0HH0 molded case circuit breaker, 100 A rated current, 3-pole, line protection, 121 kA at 240 V.
