Rated insulation voltage Ui is 800 V, and the interrupting curve drops to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — so the same breaker can be applied across 240–690 V systems as long as the available fault current stays under those thresholds. The 70 mm depth and 76.2 mm width match the standard 3VA fixed-mount footprint; it bolts directly onto the same busbar or mounting plate as other 3VA frames without re-drilling. ## Thermal derating — what the 100 A means in a warm panel 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. ## What is not on this variant No auxiliary contact block is fitted (auxiliary contact version: Without), no trip indicator, no voltage trigger, no phase-failure detection, and no communication function. The only auxiliary release is the undervoltage release (UVR). If you need a shunt trip, auxiliary contacts, or an electronic trip unit, this is not the variant — the 3VA1110-5EE32-0JA0 carries a different release and auxiliary-contact configuration. The UVR coil (order code 3VA9608-0BB24 for the integrated auxiliary trip) is factory-fitted; verify the control-voltage rating matches your circuit before applying power.","metaTitle":"Siemens 3VA1110-5EF32-0CA0 SENTRON MCCB, 100 A, 187 kA at 24","metaDescription":"Siemens SENTRON 3VA1110-5EF32-0CA0 molded case circuit breaker, 100 A rated continuous current, 187 kA interrupting at 240 V. 3-pole, line protection, undervoltage release.
