63 A MCCB with TM210 release and undervoltage trip
The Siemens SENTRON 3VA1063-2ED36-0BA0 is a 3-pole molded case circuit breaker rated for 63 A continuous current at 40 °C, with a TM210 thermal-magnetic overcurrent release and an integrated undervoltage release (UVR). Breaking capacity runs 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — so it handles high-fault scenarios across common industrial voltage levels without cascading upstream.
Thermal derating and mechanical endurance
Full 63 A rating holds up to 50 °C ambient; above that it steps down: 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. That's about a 10 % drop from the nameplate at the top end — factor that into panel thermal budgets.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — fits standard SENTRON 3VA panel cutouts and busbar systems. No auxiliary contacts on this variant; the only integrated accessory is the undervoltage release (UVR). The TM210 release is fixed thermal-magnetic — no electronic adjustment, no communication function, no phase-failure detection. It's a straight line-protection breaker for straightforward feeder or distribution duty.
