For DC switching, the contactor is rated 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — useful for controlling DC brake coils or solenoid valves in mixed-voltage panels.
The S2 frame measures 55 mm wide by 112 mm high by 115 mm deep, fitting standard 35 mm DIN rail. Terminals accept solid conductors 2x (0.25 to 2.5 mm²) and stranded conductors 2x (0.75 to 25 mm²).
The contactor is rated for 50 Hz operation.
Yes, it snaps onto 35 mm standard mounting rail per DIN EN 50022, using both screw and snap-on fastening. Side-by-side mounting is allowed.
