The Siemens SENTRON 3VA2010-5KP32-0KL0 is a 3-pole molded case circuit breaker (MCCB) rated for 100 A continuous current, designed for line protection in industrial and commercial distribution panels. It carries a maximum interrupting rating of 187 kA at 240 V, dropping to 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3 kA at 690 V — the SCCR headroom you need for high-fault utility feeds or transformer secondaries.
Thermal performance and panel fit
This MCCB holds its full 100 A rating across the entire ambient range from 40 °C through 70 °C — no derating curve to calculate for a warm enclosure. The frame measures 86 mm deep by 105 mm wide by 181 mm tall, so it fits standard 3-pole MCCB mounting footprints in switchboards and panelboards. Power dissipation is 13.5 W maximum, manageable for thermal coordination in a multi-breaker lineup.
Auxiliary and communication capability
Factory-fitted with 2 auxiliary switches, 1 trip alarm switch, and 1 electrical alarm switch (HQ configuration), plus a shunt trip (STL) for remote opening. The breaker also carries a communication function onboard — no separate module needed for integration into a BMS or SCADA system. Undervoltage release is not included in this variant.
