The 45 kW AC-2 at 400 V rating tells you it handles wound-rotor motors or slip-ring applications where the load current stays near the motor rating during acceleration — a common fit for crane or conveyor drives. Screw-type terminals on the main circuit accept stranded conductors up to 2x 50 mm² and solid up to 2x 4 mm², so it lands comfortably on a 35 mm² motor cable without lug adapters. The IP20 front with cover or box terminal means the panel builder can leave the front exposed inside a locked enclosure — no extra shrouding needed. No need to gut the whole line — meet it where it is.
The part carries a substance prohibitance date of 05/01/2012, which aligns with RoHS compliance.
Integration notes
Dimensions are 146 mm high, 70 mm wide, 139 mm deep. Maximum switching frequency at AC-3 is 850 cycles per hour, which is adequate for most conveyor and pump cycling.
