It carries a 24 VDC coil and mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a compact footprint of 45 mm wide by 85 mm tall by 151 mm deep.
The contactor is rated for switching frequencies up to 1 000 cycles per hour in AC-1 resistive duty, 750 in AC-2 and AC-3 motor duty, and 250 in AC-4 plugging/reversing — that 750 c/h AC-3 figure is the one to size for a standard conveyor or pump motor start. Operating altitude maxes out at 2 000 m without derating.
The depth is 151 mm, with a width of 45 mm and height of 85 mm.
The screw terminals accept 1 to 10 mm² solid or stranded copper wire.
Yes, it mounts via screw or snap-on onto 35 mm standard mounting rail per DIN EN 60715.
The maximum operating altitude is 2 000 m.
