MCCB for line protection — 63 A, 3-pole, TM210 release
The Siemens SENTRON 3VA1063-4ED36-0CH0 is a 3-pole molded case circuit breaker rated for a continuous current of 63 A at 40 °C, with the TM210 thermal-magnetic release tuned for line protection. The interrupting capacity reaches 121 kA at 240 V and 75.6 kA at 415 V, giving selectivity headroom for most distribution panels.
Above that, derating is progressive: 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.
The UVR coil is designed for undervoltage protection; the auxiliary contact set provides status feedback for PLC or indication circuits. The auxiliary release order code is 3VA9608-0BB24.
