Breaking capacity is the headline number here: 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V. No undervoltage release or ground-fault module on this variant — those are separate order-code options if your spec calls for them. ## Sizing and thermal reality At 55 °C it drops to 98 A, at 60 °C to 96 A, at 65 °C to 94 A, and at 70 °C to 91 A. If your panel is in a hot mezzanine or near a furnace line, use the 70 °C figure for your load calculation. Max power loss is 25 W. ## Panel fit Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB envelope that drops into most DIN-rail or panel-mount SENTRON bases without re-drilling. The 25 W dissipation is low enough that side-by-side mounting at 40 °C ambient is fine; above that, follow the derating curve.","metaTitle":"Siemens 3VA1110-4EF36-0HC0 SENTRON MCCB, 100A, 3-Pole, 121kA","metaDescription":"Siemens 3VA1110-4EF36-0HC0 SENTRON molded case circuit breaker, 100A at 40°C, 3-pole, 121 kA at 240 VAC.
