The Siemens SENTRON 3VA2163-6HL36-0KH0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. The interrupting capacity is the headline: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. Those numbers tell you this breaker can handle high-fault locations like a transformer secondary or a large panel main.
Built-in accessories and fit
That means you get remote tripping capability and status feedback out of the box — no field-assembly of add-on modules. The base switch variant is 3VA2163-6HL36-0AA0, so the -0KH0 suffix adds the shunt trip and auxiliary contacts at the factory. The breaker measures 105 mm wide, 181 mm tall, and 86 mm deep — standard 3-pole MCCB footprint for a SENTRON 3VA frame.

The trip indicator and voltage trigger are present, so you get visual and electrical trip indication.
