It's built in the S00 frame size, which is the compact footprint for contactors up to about 7 kW at 400 V. The 80 mm depth and 45 mm width let it fit in shallow enclosures or tight DIN-rail groupings. Stand-alone installation means it mounts independently, not just as a contactor add-on — useful for retrofit or panel layouts where the contactor is already placed. The relay operates from -40 to +70 °C and survives transport down to -55 °C, so it's fine for cold storage or outdoor cabinet applications.
Both main and auxiliary circuits use screw-type terminals. Main terminals accept 2x (0.5...1.5 mm²) solid/stranded or 2x (0.75...2.5 mm²), with AWG equivalents of 2x (20...16), 2x (20...18), and 2x 12. Tightening torque is 0.8...1.2 N·m — don't overtighten or you'll strip the threads in the thermoplastic body. Auxiliary terminals take 2x (0.5...1.5 mm²) or 2x (0.75...2.5 mm²). The 6 mm required side spacing to grounded parts is the minimum air gap — account for it in the wiring trough layout.
