Screw-type terminals on the main circuit accept solid conductors 2×(0.5…1.5 mm²) and 2×(0.75…2.5 mm²), or stranded 2×(1…2.5 mm²) and 2×(2.5…6 mm²) — covers standard panel wire up to 6 mm² for the load side.
Operating temperature range is -20 to +60 °C, storage and transport range -50 to +80 °C — suitable for unheated plant floors and cold warehouses as long as the ambient stays above -20 during operation. Shock resistance rated at 25 g for 11 ms, and the mechanical endurance of the main contacts is 100 000 cycles typical — enough for frequent-start applications like conveyors or compressors. Maximum altitude for rated operation is 2 000 m; above that, derating applies for air insulation and cooling.
