It carries a 187 kA interrupting rating at 240 V, dropping to 121 kA at 415 V and 75.6 kA at 440 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream breakers. This breaker includes an undervoltage release and a universal release (UNI) auxiliary, plus two HQ auxiliary switches — so it's ready for shunt-trip or UVR control schemes without adding external accessories. ## Thermal derating and real-world load The 100 A rating holds flat from 40 °C through 50 °C (-), then derates to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C (-). That's a gentle slope — losing only 9 A over a 20 °C rise — which means a panel running at 55 °C ambient still carries a 98 A continuous load. If your enclosure sits near a furnace or in a hot attic, you still get nearly full rating. Maximum power loss is 27.5 W, so the heat it dumps into the panel is modest for a 100 A frame. That 3-inch width is standard for a 100 A 3-pole MCCB — it fits the same DIN-rail or panel-mount footprint as other SENTRON 3VA1 frames.","metaTitle":"Siemens 3VA1110-5EE32-0LC0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1110-5EE32-0LC0 molded case circuit breaker, 100 A continuous, 3-pole, 187 kA interrupting at 240 V.
