The Siemens SENTRON 3VA2010-5JQ32-0JL0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a continuous current of 100 A across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3 kA at 690 V, giving the panel designer a single frame that covers high-fault service-entrance and downstream feeder duty without a second device.
Breaking capacity and selectivity planning
At 415 V the 121 kA interrupting rating places this MCCB well above typical utility fault levels for industrial distribution — the buyer specifying against a 65 kA or 100 kA SCCR bus gets headroom for full selectivity with downstream breakers. The 3 kA at 690 V is a low-endurance limit; this frame is not intended for 690 V main service. The 100 A rating is flat from 40 °C to 70 °C, which simplifies panel thermal calculations in non-conditioned enclosures.
Auxiliary and release configuration
Factory-fitted with two auxiliary switches, one trip alarm switch, and one electrical alarm switch (HQ type), plus a shunt trip release (STL). This combination covers remote status and emergency trip without adding aftermarket modules — a time-saver for panel builders wiring safety circuits or PLC-driven shutdown sequences.
Physical fit and panel integration
Dimensions are 105 mm wide, 181 mm high, and 86 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or bolt-on panel layouts. The 13.5 W maximum power loss at rated load should be factored into enclosure thermal rise calculations.
