Mounting is screw or snap-on onto 35 mm DIN rail per DIN EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward, so it fits tight enclosures without a special bracket. Physical footprint is 45 mm wide, 70 mm high, 73 mm deep — the depth matters for gland-plate clearance if you're panel-building to a shallow backplate.
Rated operational current at 24 V DC is 10 A, dropping to 3 A at 400 V DC and 0.2 A at 440 V DC — the inductive DC load curve is steep, so don't assume the 24 V figure holds at higher voltages. For AC-3 motor switching, the maximum operating frequency is 750 cycles per hour; AC-4 (inching/plugging) drops to 250 cycles per hour. If your application needs frequent jogging, that 250 c/h limit is the hard stop — the contactor's mechanical life of 30 million operations won't be the constraint, the arc-erosion rate at AC-4 will be.
Wire termination and environmental limits
Spring-type terminals accept solid or stranded wire from 0.5 to 4 mm², and up to 2x (0.5 to 4 mm²) per clamp — useful for daisy-chaining control wiring without a separate terminal block.
