Product details

It carries 2 normally open and 2 normally closed instantaneous contacts, rated 10 A at 24 V and 6 A at 230 V. The 45 mm wide body mounts via screw or snap-on to DIN rail, and the IP20 front protection suits enclosed panel environments.

The 10 A rating at 24 V covers the majority of PLC output and relay coil loads in control panels — that's the figure that decides whether this contactor can handle your signal circuit without an intermediate relay. At 230 V it's rated 6 A, so it switches contactor coils and small valve solenoids directly. The 690 V rating drops to 1 A, which still covers most auxiliary contact applications in 400 V motor starters.

The 45 mm width and 72 mm depth fit the standard Size S00 footprint used across the SIRIUS contactor family. Screw terminals accept solid conductors: 2x 0.5 to 1.5 mm², 2x 0.75 to 2.5 mm², or 2x 4 mm². Mounting position is standing on a horizontal surface, fastened by screw or snap-on.
