Line protection MCCB with shunt trip
The Siemens SENTRON 3VA2010-5HL36-0HA0 is a 3-pole molded case circuit breaker rated for 100 A continuous current, designed for line protection in distribution panels. Its interrupting capacity reaches 187 kA at 240 V AC and 121 kA at 415 V AC, meaning it can safely clear high-fault currents on a 400 V class industrial feeder without upstream coordination issues. The built-in shunt trip (STL) auxiliary release allows remote tripping from a PLC or emergency-stop circuit — useful for process lines where a safety signal must drop the breaker independently of the overload curve.
Thermal performance and panel fit
The breaker carries 100 A continuously across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Maximum power loss is 13.5 W, which matters for enclosure heat rise calculations when multiple breakers are ganged. Dimensions are 181 mm tall, 105 mm wide, and 86 mm deep, fitting a standard MCCB footprint. The supplied basic switch is order code 3VA20105HL360AA0.
