The Siemens SENTRON 3VA2163-6HN32-0JA0 is a 3-pole molded case circuit breaker rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling. Interrupting capacity hits 242 kA at 240 V, 187 kA at 415 V, and still holds 121 kA at 500 V; at 690 V it drops to 3.7 kA, so keep that in mind for higher-voltage taps. The built-in shunt trip (STL) lets you remote-trip via a control signal — handy for emergency-stop chains or undervoltage coordination without adding an external relay.
Panel Fit and Mounting
Dimensions are 105 mm wide, 181 mm tall, 86 mm deep — that 86 mm depth is the key number for enclosure depth clearance when the breaker is mounted on a DIN rail or bolted to a backplate. The 105 mm width means it occupies three standard 35 mm pole spaces, so it drops into a panel that was laid out for a 3-pole SENTRON frame without surprises.
