The Siemens 3VA2010-5KP32-0AB0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling, which simplifies the panel thermal budget. Its interrupting capacity hits 187 kA at 240 V AC, dropping to 121 kA at 415 V and 440 V, then 75.6 kA at 500 V, and 3 kA at 690 V. The line-protection design targets feeder and main breaker roles, not motor branch-circuit protection. Communication function is onboard, so it can report trip status and current values to a PLC or SCADA without an add-on module.
The supplied basic switch is 3VA20105KP320AA0. Two auxiliary switches HP are included, giving status feedback without extra wiring.
