Product details

It mounts via screw or snap-on onto standard 35 mm DIN rail, and the mounting position allows +/-180° rotation on a vertical surface plus +/-22.5° tilt forward and backward, so it fits tight enclosures without reworking the panel layout.

Rated at 10 A at 24 V, this contactor handles typical PLC output loads, pilot lights, and small solenoid valves without an interposing relay. Arcing time runs 10 to 15 ms, so the contact gap clears quickly enough to protect downstream solid-state inputs from prolonged arc energy.

Mounting and Spacing

The 45 mm width and 73 mm depth let it nest alongside S00 contactors on the same DIN rail without crowding. Clearance requirements: 10 mm upwards, 10 mm forwards, 10 mm downwards, 6 mm at the side. That means you can pack three of these across a 140 mm DIN section and still have room for wiring ducts. The screw terminals accept 2x 0.5 to 4 mm² solid or stranded wire, so no special ferrules needed for standard control wiring.

Frequently asked questions

What are the key dimensions for panel layout?

Width is 45 mm, depth is 73 mm, height is 70 mm. Clearance required: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the side.

What is the rated current at 24 V?

The rated value at 24 V is 10 A. At 230 V the rated value is also 10 A, and at 400 V it is 3 A.

Does this contactor have a RoHS or substance compliance date?

The substance prohibitance date is listed as 10/01/2009, which aligns with RoHS compliance requirements.
