The Siemens SENTRON 3VA1063-2ED42-0HA0 is a 4-pole molded case circuit breaker (MCCB) rated for line protection, carrying 63 A continuously at 40 °C without derating. The TM210 thermal-magnetic release handles overload and short-circuit protection in one package — no separate relay needed. A built-in shunt trip (STL) allows remote tripping from a PLC safety output or emergency-stop button, which is useful for coordinated shutdown sequences in a panel.
Breaking capacity by voltage
This MCCB interrupts 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The 52.5 kA figure at 240 V covers high-fault utility feeds common in North American 120/240 V split-phase panels; the 32 kA at 415 V suits European 400 V distribution where transformer impedance keeps fault levels lower. The 7.5 kA at 690 V is adequate for industrial 690 V drives and motor control centers — verify the available fault current at the point of installation stays under that threshold.
Thermal derating and ambient limits
Rated current holds flat at 63 A from 40 °C through 50 °C, then drops to 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. If the breaker lives in a non-ventilated enclosure near transformers or drives, the 58 A at 70 °C figure is the one to size against — not the 63 A nameplate. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
Panel fit and dimensions
The breaker measures 130 mm high, 101.6 mm wide, and 70 mm deep. The 4-pole width (101.6 mm) matches the standard 100 mm MCCB footprint for DIN-rail or panel-mount installation — verify the busbar spacing and enclosure cutout against the existing panel layout before ordering. The 70 mm depth leaves clearance for rear-connected busbars and wiring troughs.
Key specs at a glance
Rated insulation voltage is 800 V. Maximum power loss is 17.3 W. The overcurrent release is TM210 (thermal-magnetic, fixed thermal and magnetic settings). No communication function, no undervoltage release, no ground-fault monitoring. The supplied basic switch is 3VA10632ED420AA0. The product is designed for line protection — not motor protection (no overload class or phase-loss sensitivity).
