SENTRON 3VA2 MCCB, 63 A Frame, Shunt Trip
The Siemens 3VA2163-6HN36-0HA0 is a SENTRON molded case circuit breaker (MCCB) in a 3-pole configuration, rated for a continuous current of 63 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to the frame limit. The interrupting capacity hits 242 kA at 240 VAC and still holds 187 kA at 415/440 VAC, which gives solid selectivity headroom in high-fault industrial panels. The supplied basic switch is order code 3VA2163-6HN36-0AA0, which is the base breaker without the shunt trip module.
Interrupting Capacity and Selectivity
At 240 VAC the breaker interrupts 242 kA symmetrical; at 415 V and 440 VAC it still manages 187 kA. That drops to 121 kA at 500 VAC and to 3.7 kA at 690 VAC.
