The Siemens SENTRON 3VA2110-5KP32-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous at 40 °C, with an adjustable thermal-magnetic trip unit covering 150 A to 1 200 A. The interrupting ratings are substantial: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That SCCR headroom means it can handle high-fault-capacity mains without cascading upstream. The basic switch module is order code 3VA21105KP320AA0.
Sizing and thermal performance
That simplifies panel design in warm enclosures or near other heat sources. Maximum power loss is 12.5 W, which is modest for a 100 A frame.
The trip indicator is present, and the unit has no voltage-trigger function. Ground-fault monitoring is not included on this variant.
