Product details

It mounts on a 35 mm DIN rail per DIN EN 60715 via screw and snap-on fastening, and its 45 mm width and 97 mm depth fit standard panel layouts without crowding adjacent devices.

Rated at 10 A at 24 V and 7.6 A at 480 V, this contactor handles moderate motor and general-purpose loads. The S0 frame means the contactor is physically compact enough for high-density layouts but still carries auxiliary switch provisions. Operating temperature range of -25 to +60 °C and storage range of -55 to +80 °C suit unheated enclosures and warehouse conditions. The mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward/backward, giving flexibility in tight enclosures.

Clearance requirements: 10 mm upward, 10 mm forward, 10 mm downward, and 6 mm at the side. These spacings ensure proper arc quenching and heat dissipation. The contactor is rated for 1000 switching cycles per hour under AC-1, AC-2, AC-3, and AC-3e duty, and 300 cycles per hour under AC-4 duty.

Frequently asked questions
