It carries a continuous current Iu of 63 A and uses a TM210 thermal-magnetic release with fixed short-circuit pickup at 630 A (LI characteristic). Rated insulation voltage Ui is 500 V, and the maximum DC operating voltage is 125 V. The breaker is 25.4 mm wide (one standard pole width) and 70 mm deep, so it fits a standard DIN-rail enclosure without crowding adjacent poles.
The 63 A rating holds at 45 °C and 50 °C. At 55 °C it derates to 62 A, at 60 °C to 61 A, at 65 °C to 60 A, and at 70 °C to 58 A. Operating ambient range is -25 °C to 70 °C; storage range is -40 °C to 80 °C.
At 25.4 mm wide, this breaker occupies one standard pole pitch on a DIN rail. Depth of 70 mm leaves clearance for wiring gutters in most enclosures.
