Line protection MCCB with TM210 and shunt trip
The 3VA1063-2ED32-0KH0 is a Siemens SENTRON 3-pole molded case circuit breaker rated for line protection at 63 A continuous current (40 °C ambient, no derating up to 50 °C).
Interrupting ratings across common voltages
At 240 V it clears 52.5 kA; at 415 V — the most common industrial low-voltage supply — it interrupts 32 kA. That puts it in a solid range for most distribution panels behind a transformer of moderate size. At 440 V it drops to 13.6 kA, and at 690 V it still holds 7.5 kA, which matters if you are on a 690 V mining or marine system.
Current derating and ambient temperature
The breaker holds full 63 A from 40 °C up through 50 °C without any derating — that covers most ventilated enclosures. Above that, it drops: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. If you are packing this into a hot cabinet or near other heat sources, account for that taper.
Depth is 70 mm, so it does not stick out far from the mounting surface. The auxiliary contact block (2 form-C aux + 1 trip alarm) is integrated; the shunt trip coil is specified separately as 3VA9688-0BL33 if you need a replacement or spare.
