The Siemens SENTRON 3VA2163-5MN36-0JC0 is a 3-pole molded case circuit breaker (MCCB) rated for 63 A continuous current across the full ambient range from 40 °C to 70 °C — no derating needed up to that ceiling.
The interrupting ratings are given at several voltages. At 415 V the breaker clears 121 kA symmetrical; at 240 V it handles 187 kA. Those figures drop to 75.6 kA at 500 V and to 3.7 kA at 690 V. The short-time delay band (4 s minimum, 17 s maximum) allows coordination with downstream motor starters during start-up transients.
Integration and panel fit
The shunt trip release allows a remote pushbutton or safety relay to open the breaker without a manual handle pull. Maximum power loss is 4 W.
