The Siemens SENTRON 3VA2163-7MN32-0HA0 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. Breaking capacity is the headline here: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
Sizing and trip characteristics
The thermal-magnetic trip operates with a minimum delay of 4 s and a maximum of 17 s under fault conditions, which gives selectivity headroom against downstream branch breakers. The basic switch variant is 3VA2163-7MN32-0AA0; this -0HA0 suffix adds the shunt trip release. No auxiliary switch or ground-fault monitoring is included on this version — those are separate add-on modules.
