It handles a maximum continuous current of 500A with a rated value of 450A at 690V AC, 50/60 Hz — sized for the input side of large drives or regenerative converters where the switching edges need smoothing and the fault current must be limited. The 625A peak current rating covers short-duration overloads during motor acceleration or line transients.
Thermal and mechanical fit
Rated for 40°C ambient with thermal class H (180°C insulation system) per IEC 60085 — the winding can run hot under full load without degrading the insulation life. Total power loss splits into 390W in the coil and 180W in the iron core, so the panel needs to vent or force-air cool that 570W combined heat load. IP00 protection means it is an open-frame component — no enclosure, no ingress protection. Mount it inside a cabinet with clearance around the flat-type terminals (main current circuit connection) for busbar or cable lugs. Dimensions are 0.35m wide × 0.321m tall × 0.227m deep; plan the gland plate and busbar routing accordingly.
