At 240 V AC, the 3VA1110-4EF32-0AH0 interrupts 121 kA symmetrical — that is a very high rating for a 100 A frame, suited for high-fault utility or transformer-fed service entrances. At 415 V it still clears 75.6 kA, and at 690 V it holds 11.9 kA. The 3-pole construction handles three-phase loads. ## Thermal Derating and Ambient Operating Range Above that, the continuous current must be reduced: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. This is a standard thermal-magnetic characteristic — the bimetal element responds to both load current and enclosure ambient. ## Physical Fit and Auxiliary Switching Depth of 70 mm (2.76 in) fits within typical distribution cabinet clearances. This provides status feedback for the open/closed position and a separate signal for trip events — useful for remote monitoring or PLC inputs. No undervoltage release or shunt trip is included on this variant; those are separate accessories. A trip indicator is present on the front face, giving a visual flag when the breaker has opened on fault versus manual switching.","metaTitle":"Siemens 3VA1110-4EF32-0AH0 SENTRON MCCB, 100A, 3-Pole, 121kA","metaDescription":"Siemens 3VA1110-4EF32-0AH0 SENTRON molded case circuit breaker, 100A rated at 40°C, 3-pole, TM240 release, 121kA breaking at 240V.
