The contactor mounts on 35 mm DIN rail per DIN EN 60715, either screwed or snapped on, and the mounting position allows ±180° rotation on a vertical surface plus ±22.5° tilt forward and backward.
AC-3 maximum switching frequency is 750 cycles per hour, and AC-4 drops to 250 cycles per hour — that's the difference between running a motor on/off versus plug-reversing or inching duty. If your application needs frequent jogging, the AC-4 limit is the one that governs thermal rise in the contactor. Spring-cage terminals accept solid or stranded wire from 1 to 10 mm², and double up to 2x (0.5... 2.5 mm²) for daisy-chaining. Strip length is standard for cage clamps — no special tool needed. The 45 mm width and 97 mm depth fit a standard S0 footprint; clearance at the side is 6 mm, and 10 mm above/below for airflow and wiring access.
This contactor is built for a control panel — DIN-rail mounted, spring-cage wiring, no screw terminals to torque. Operating temperature range is -25 to +60 °C, storage from -55 to +80 °C, so it's fine in an unheated enclosure as long as it's not running below -25. The coil hold-in voltage is 24 VDC rated at 10 A (the inrush is higher but the sealing current is what the control transformer sees).
