Its 4-pole configuration and TM210 thermal-magnetic release make it suitable for protecting feeders and branch circuits in distribution panels. The interrupting ratings 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 — figures that govern its fault-clearing capability at the system voltage present.
The 63 A rating holds up to 50 °C ambient; above that, the continuous current derates to 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. For panel builders, this means the breaker can be applied at its full nameplate in most ventilated enclosures, but a high-ambient compartment (e.g., adjacent to a drive or transformer) requires a downward adjustment.
Auxiliary contacts and trip indication
The trip indicator is present on the front face, aiding field-service techs during fault isolation.
The 3VA1063-3ED42-0AH0 measures 130 mm high, 101.6 mm wide, and 70 mm deep. The 70 mm depth is a key dimension for gland-plate clearance and shallow enclosure fit. Front protection class is IP40, suitable for general-purpose indoor panels. The 4-pole width (101.6 mm) matches the standard 100 mm grid for DIN-rail or mounting-plate layouts; verify busbar and lug spacing against the existing panel cutout.
