What this MCCB delivers for the panel
The Siemens 3VA2010-6HL32-0AG0 is a 3-pole SENTRON molded case circuit breaker rated for 100 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed as the panel warms up. Its adjustable thermal-magnetic trip unit covers 150 A to 1 200 A, so you set the instantaneous pickup to coordinate with downstream branch breakers. The interrupting ratings climb to 242 kA at 240 V and 187 kA at 415 V, giving solid SCCR headroom for high-fault service-entrance or distribution panels. Rated insulation voltage is 800 V, and the design is explicitly for line protection — meaning it sits at the incoming feed, not on a motor branch. The built-in trip indicator and auxiliary switch (1 auxiliary + 1 trip alarm) give the PLC or BMS a hard contact on fault events, which speeds root-cause isolation on a down line.
Panel fit and integration
The breaker measures 105 mm wide by 181 mm tall by 86 mm deep — a standard 3-pole MCCB footprint that fits most distribution panelboards and enclosure backplates without a sub-panel adapter. Max power loss is 13.5 W, so internal cabinet heating stays manageable; no forced ventilation required in a typical 600 mm × 800 mm enclosure. Storage range is -40 °C to 80 °C; operating range is -25 °C to 70 °C.
