What this MCCB delivers in the panel
The Siemens 3VA2163-6HL32-0KA0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current across the full 40 °C to 70 °C ambient range — no derating needed until you push past that band. Three poles, line-protection design, and a shunt trip (STL) auxiliary release built in.
Panel fit and environment
Footprint: 105 mm wide, 181 mm tall, 86 mm deep. Three-pole frame mounts on a DIN rail or panel-mount plate in a standard distribution board. The shunt trip coil requires a control voltage to fire — wire it to an E-stop or a safety relay circuit for remote trip capability. No communication function on this variant, so it's a standalone overcurrent protector with a remote trip input.
