Product details

It carries a 2 hp rating at 230 V, making it a fit for small motors on pumps, fans, and conveyors. The S00 frame keeps the footprint tight at 45 mm wide, 58 mm tall, and 73 mm deep — it slides onto a 35 mm DIN rail per DIN EN 60715 with either screw or snap-on mounting. That's a standard panel integration; no special brackets needed.

The contactor's switching frequency depends on the duty class. For AC-3 motor starting, it handles up to 750 operations per hour; for AC-4 inching or plugging, that drops to 250 per hour. That means if you're running a conveyor that cycles every few seconds, stay within the AC-3 limit. The auxiliary contact ratings are given at several voltages: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 0.2 A at 440 V. These are the switching limits for the built-in auxiliary switch — use them to size your PLC input or relay coil draw. At 400 V the auxiliary is rated 3 A, which covers most contactor feedback circuits. Wire termination uses screw-type terminals on the coil and main contacts. The terminals accept solid or stranded wire from 0.5 to 4 mm², and you can double up two conductors per clamp (2x 0.5-1.5 mm², 2x 0.75-2.5 mm², or 2x 4 mm²). That helps when you need to daisy-chain control power without adding a terminal block.

Mounting position is flexible — the contactor can be hung on a horizontal surface or mounted vertically. These are the minimum air gaps to maintain for heat dissipation and arc quenching; don't cram it tighter in a dense panel.

Frequently asked questions

What are the key dimensions for panel layout?

The contactor measures 45 mm wide, 58 mm tall, and 73 mm deep. Minimum clearance around it is 10 mm up/down/forward and 6 mm at the sides.

What wire sizes does the screw terminal accept?

Solid or stranded wire from 0.5 to 4 mm². It also accepts two conductors per clamp: 2x 0.5-1.5 mm², 2x 0.75-2.5 mm², or 2x 4 mm².

Does this contactor include an auxiliary contact?

Yes, it comes with a built-in auxiliary switch. Its ratings vary by voltage: 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.2 A at 440 V.

What is the switching frequency for motor duty?

In AC-3 duty (motor starting), the maximum is 750 operations per hour. For AC-4 (inching/plugging), it's 250 per hour. AC-1 resistive load switching is 1,000 per hour.
