63 A MCCB for Motor Protection — SENTRON 3VA2 Frame
The interrupting capacity hits 330 kA at 240 V, dropping to 242 kA at 415 V and 440 V, and 187 kA at 500 V; at 690 V it still holds 3.7 kA, covering most industrial supply voltages. The phase-failure detection and trip indicator are built in, so it handles the typical motor-protection coordination without an external relay. The basic switch variant is 3VA2163-7MN36-0AA0.
Dimensions are 86 mm deep, 105 mm wide, and 181 mm high — a standard 3-pole MCCB footprint for the SENTRON 3VA2 frame. The undervoltage release coil and auxiliary wiring terminals are accessible from the front, so panel wiring and troubleshooting don't require pulling the breaker.
