The breaking capacity tells you where it can safely interrupt a fault: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. The TM240 release is adjustable — you set the thermal pickup within the 63 A frame rating to match your load. The 63 A rating holds flat from 40 °C up to 50 °C, then derates slightly: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, 56.7 A at 70 °C. If your panel runs hot, factor that derating into your load calculation. That means if your control voltage drops below the dropout threshold, the breaker trips automatically, which is common for emergency-stop circuits or undervoltage protection on motor feeders. The integrated auxiliary trip uses order code 3VA9608-0BB24 if you need to replace that sub-assembly. Mechanical endurance is rated at 15,000 cycles — that's the number of open-close operations the mechanism is tested for before wear becomes a concern. For a feeder breaker that cycles maybe a few times a year, that's plenty. For a frequently switched load, keep it in mind.","metaTitle":"Siemens 3VA1163-3EF32-0CH0 SENTRON MCCB, 63 A, 3-pole, TM240","metaDescription":"Siemens SENTRON 3VA1163-3EF32-0CH0 molded case circuit breaker, 63 A rated, 3-pole, TM240 thermal-magnetic release, 75.6 kA at 240 V.
