What sets this MCCB apart is the interrupting capacity: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. ## Thermal derating and endurance — the real-world operating envelope The 100 A rating holds flat from 40 °C to 50 °C ambient; above that, the continuous current must be reduced per the datasheet curve — 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C. The latching endurance is rated at 20,000 operations — that's the mechanical life before the latch mechanism wears, not the electrical endurance under load. For frequent switching, factor in the electrical life at your specific fault level. The maximum power loss is 12.5 W, which matters for heat buildup inside a sealed enclosure. ## Built-in undervoltage release and auxiliary contacts That alarm contact is useful for remote fault annunciation without wiring through the main breaker position. The basic switch assembly is orderable separately as 3VA2110-5HN36-0AA0 if you need a replacement mechanism. Dimensions: 181 mm height, 105 mm width, 86 mm depth. The depth of 86 mm includes the arc chamber and terminal clearance; verify that the enclosure depth leaves room for cable bending radius behind the breaker.","metaTitle":"Siemens 3VA2110-5HN36-0BH0 SENTRON MCCB, 100 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA2110-5HN36-0BH0 molded case circuit breaker, 100 A, 3-pole, ETU350 release, interrupting 187 kA at 240 V.
