This is the line protection variant — meaning it's configured for feeder and main distribution protection, not motor or generator duty. The interrupting ratings climb to 121 kA at 240 V and 75.6 kA at 415 V, so it handles high-fault utility feeds without cascading upstream. At 55 °C it drops to 60.48 A, and at 70 °C it's 56.7 A. That's a gentle slope; you can still run 60 A through it at 60 °C. The SCCR curve matters for selectivity: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. If your transformer secondary is 480 V with 65 kA available fault current, this breaker covers it with headroom. ## Integrated auxiliary contacts and undervoltage release The undervoltage release (UVR) is also built in, so the breaker drops out if control voltage falls below the dropout threshold. The auxiliary contact version is factory-set; verify the wiring diagram matches your PLC input mapping before panel wiring. Dimensions: 130 mm height, 101.6 mm width, 70 mm depth.","metaTitle":"Siemens 3VA1063-4ED42-0CH0 SENTRON MCCB, 63 A, 4-Pole, 121 k","metaDescription":"Siemens SENTRON 3VA1063-4ED42-0CH0 molded case circuit breaker, 63 A rated, 4-pole, line protection with TM210 release. 121 kA at 240 V, 75.6 kA at 415 V.
