The 800 V rated insulation voltage (Ui) gives headroom for 690 V line-to-line systems, though the interrupting rating at 690 V drops to 7.5 kA, so verify the available fault current if you're pushing that voltage class. It does not have a voltage trip, phase-failure detection, ground-fault monitoring, or any communication module — it's a straightforward line-protection breaker, not a multifunction power monitor. Dimensions are 70 mm deep, 101.6 mm wide, and 130 mm tall — a 4-pole footprint that fits standard SENTRON mounting rails. ## Thermal derating — the real-world current you can actually run At 55 °C it derates to 60.48 A, at 60 °C to 59.22 A, at 65 °C to 57.96 A, and at 70 °C to 56.7 A. If your panel ambient sits above 50 °C — say a sealed enclosure near a furnace line — you lose roughly 0.6 A per degree. Plan the load accordingly; the breaker won't trip early, but you'll be running it above its calibrated thermal curve. ## What the TM210 release means for coordination The TM210 designation indicates a thermal-magnetic release with a fixed thermal pickup and a magnetic short-circuit trip set at 10× Iu (630 A). That's a standard curve for motor-circuit or distribution feeders where you want the magnetic element to ignore inrush and only clear hard faults. For selective coordination downstream, pair it with a breaker whose instantaneous trip is below 630 A; upstream, ensure your main has a higher magnetic pickup or a short-time delay.","metaTitle":"Siemens 3VA1063-3ED42-0BC0 SENTRON MCCB, 63 A, 4-pole, 75.6","metaDescription":"Siemens SENTRON 3VA1063-3ED42-0BC0 molded case circuit breaker, 63 A rated current, 4-pole, 75.6 kA at 240 V.
