It mounts via screw and snap-on onto a 35 mm DIN rail per EN 50022, fitting into a 45 mm wide slot with 57.5 mm height and 72 mm depth — a compact footprint for dense panel layouts. The IP20 front and terminal protection means it's suited for enclosed cabinets where no washdown exposure occurs.
For general resistive or motor starting (AC-3), the 24 V coil pulls 3.3 W closing and holding power, so the control transformer or DC supply must deliver that continuously. The main circuit accepts screw terminals with wire sizes up to 2x (0.75...4 mm²) solid or stranded, or AWG 12 single conductor — no ferrule crimping needed for stranded if using the screw clamp correctly.
The screw terminals accept 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²) solid/stranded, and up to 1x 12 AWG for the main circuit — no special tools beyond a screwdriver. For type 2 coordination, use a gL/gG 20 A fuse; for type 1, a 35 A fuse is sufficient.
