The Siemens SENTRON 3VA2010-5JQ32-0CC0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. It is designed for line protection in distribution panels and switchgear, with a breaking capacity of 187 kA at 240 V AC, stepping down to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V.
Two auxiliary switches (HQ design) are fitted for remote status indication. Communication function is present, allowing integration with a building management or SCADA system for remote monitoring and trip logging.
The 86 mm depth leaves clearance for wiring and busbar connections behind the panel door; verify gland plate depth if the breaker sits near the rear wall. Power loss is 16 W maximum at rated current, so ventilation in a sealed enclosure should account for that heat.
