The Siemens SENTRON 3VA2163-5HL36-0JC0 is a 3-pole molded case circuit breaker rated for 63 A continuous at 40 °C, with an electronic ETU320 overcurrent release. What it does have is a shunt trip (STL) and two HQ auxiliary switches, so it's ready for remote tripping and status feedback in a control panel. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. Thermal derating is gradual: full 63 A up to 50 °C, then 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C.
The auxiliary contact version is two HQ switches, which means high-quantity switching for PLC or SCADA feedback loops.
