It mounts on a 35 mm DIN rail per EN 50022 with either a snap-on clip or screws, and the S0 footprint (85 mm high, 61 mm wide, 91 mm deep) leaves room for side-by-side mounting without derating, as long as ambient stays within -25 to +60 °C operating range.
Main and auxiliary circuits use screw-type terminals that accept up to 4 mm² stranded or 2.5 mm² solid per clamp, with a double-wire capacity of 2x (0.75 to 4 mm²) for looping through without a separate jumper. Front-facing terminals are IP20 finger-safe; the terminal body itself is IP00, so keep live parts clear of grounded metal in the panel.
Switching capacity across voltages
DC switching is rated by voltage: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, and 0.3 A at 220 V — these are resistive DC values, so inductive DC loads (brakes, solenoids) need a diode or RC snubber across the coil.
