The Siemens SENTRON 3VA2116-5HN36-0KA0 is a 3-pole molded case circuit breaker rated for 160 A continuous current — that figure holds flat from 40 °C through 70 °C ambient, so no derating curve to chase in a warm enclosure. Breaking capacity is the real selector here: 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. This variant carries a factory-fitted shunt trip (STL) release for remote tripping — emergency-stop circuits or PLC-driven load shedding.
Dimensions: 181 mm high, 105 mm wide, 86 mm deep — a standard SENTRON 3VA2 frame that drops into the same mounting footprint as other 3VA2 breakers. Power loss at full rated current is 25.5 W — relevant for thermal budget in sealed or compact enclosures.
