The Siemens SENTRON 3VA2163-6HL32-0AF0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current and a breaking capacity of 242 kA at 240 V. It's designed for line protection — think main feeder or large branch circuit where you need high fault interruption without upstream coordination headaches.
That means you can mount it in a crowded enclosure without losing capacity. The 242 kA SCCR at 240 V is the maximum interrupting rating; at 690 V it drops to 3.7 kA, so verify your available fault current at the installation voltage. The 3-pole design with an integral auxiliary switch (1 aux + 1 trip alarm) gives you remote status without an add-on module.
