Product details

Integrator's field note

It mounts via screw and snap-on onto 35 mm DIN rail per EN 60715, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward/backward — useful when panel layout forces a non-standard orientation. Rated for AC-3 switching at 850 cycles per hour maximum, and AC-1 at 900 cycles per hour — the AC-3 figure governs motor-load duty; the AC-1 figure covers resistive loads. Main contact electrical life is 10 million operations typical. Conductor cross-section accepts solid 2.5…16 mm² and stranded 6…70 mm² — the stranded range covers the heavier power feed; the solid range suits the control wiring. Auxiliary switch is included as standard.

Dimensions: 152 mm depth, 70 mm width, 140 mm height. Operating temperature range -25…+60 °C; storage range -55…+80 °C.
