The Siemens 3VA1063-3ED36-0CA0 is a SENTRON molded case circuit breaker (MCCB) rated for 63 A continuous current at 40 °C, 3-pole, configured for line protection with a TM210 thermal-magnetic trip unit. This is the core overcurrent device for a feeder or branch circuit — not a motor-protective breaker with integrated phase-loss detection. The TM210 holds its full 63 A rating up to 50 °C, then derates linearly: 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 derating curve matters if this lands in a sealed, uncooled enclosure near heat sources. Short-circuit breaking capacities span 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V — enough headroom for most 400 V industrial distribution panels to meet the 50 kA SCCR target without cascading upstream.
For selectivity studies, the thermal curve is fixed, so coordination with downstream breakers depends on the manufacturer's let-through charts. No auxiliary contact block is included on this order code; if you need remote status feedback, you add a separate auxiliary switch module.
