The Siemens SENTRON 3VA2010-5JQ32-0HL0 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. It carries 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. The adjustable thermal-magnetic trip is field-set from 20 A to 100 A, with a trip indicator and voltage trigger for remote signaling. It includes a shunt trip (STL) release and an auxiliary switch configuration of two auxiliary switches plus one trip alarm switch plus one electrical alarm switch HQ. Designed for line protection, the breaker also supports communication functions for integration into monitored distribution systems.
Breaking capacity and selectivity
The 187 kA at 240 V and 121 kA at 415 V ratings place this MCCB in the high-interrupting category for commercial and light industrial panelboards. At 690 V the rating drops to 3 kA — that limits its use on 690 V systems to low-fault locations or downstream of a current-limiting device. The 100 A rating holds flat through 70 °C ambient, so no derating curve needed in a warm enclosure. The adjustable trip from 20 A allows coordination with downstream 20 A branch breakers.
Integration and mounting
The 3VA2010-5JQ32-0HL0 mounts on a DIN rail or panel with a 105 mm width, 181 mm height, and 86 mm depth. The 3-pole form factor fits standard Siemens SENTRON switchgear footprints. The shunt trip (STL) and auxiliary switch block (2 aux + 1 trip alarm + 1 electrical alarm HQ) are factory-installed; no field-assembly of internal accessories required. Power loss is 13.5 W maximum at rated load, which is manageable for a ventilated enclosure.
