The 3VA2163-5HL32-0KC0 is a Siemens SENTRON 3VA2 molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C through 70 °C — no derating needed across that band. The adjustable thermal-magnetic trip unit covers 95 A minimum to 756 A maximum, so you set it to the actual load, not the frame. Breaking capacity runs 187 kA at 240 V, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V; that 187 kA figure at 240 V handles high-fault utility feeds without cascading upstream. The internal basic switch is order code 3VA21635HL320AA0.
Panel fit and physical integration
Maximum power loss is 4 W, so heat dissipation is minimal inside the enclosure.
Trip indicator and auxiliary release detail
This variant has no trip indicator and no undervoltage release. The auxiliary release is a shunt trip (STL) — used for remote tripping via a control signal. The two auxiliary switches HQ provide status feedback for the breaker position.
