It mounts on 35 mm or 75 mm standard DIN rail via screw or snap-on fastening, which simplifies panel integration and retrofit work. Rated for AC-3 duty at 45 kW on a 500 V 50/60 Hz supply, and 21.1 kW at 690 V, this contactor handles typical motor loads like pumps, fans, and conveyors up to that power band.
The 45 kW rating at 500 V (AC-3) is the headline number for motor selection. If your motor nameplate is 45 kW or less on a 500 V line, this contactor has the thermal and switching capacity. Always match the AC-3 rating, not the AC-1 resistive rating, for motor loads. That covers most motor feeder cables up to about 35 mm² per phase. The control circuit (coil) terminals accept 2x 0.5 to 2.5 mm² solid or stranded. Pollution degree 3 confirms it's rated for conductive environments typical in industrial enclosures.
Fastens to 35 mm or 75 mm DIN rail — the 75 mm option is less common but useful for high-current panels where standard 35 mm rail might flex. Dimensions: 70 mm wide, 146 mm tall, 188 mm deep.
