The Siemens SENTRON 3VA2163-5HN32-0DA0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current of 63 A across the full ambient temperature range from 40 °C to 70 °C — no derating needed up to the panel's thermal ceiling.
Sizing and interrupting capacity
Interrupting ratings: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
The 86 mm depth leaves room behind a 200 mm deep gland plate for wiring and the UVR coil connections.
