Storage range extends to -55 °C to +80 °C, which governs handling and warehousing, not running.
For AC-3 motor switching (the standard squirrel-cage duty), it's rated at 850 operations per hour maximum; AC-4 (plugging/reversing) drops to 250 ops/h. The AC-1 resistive load rating allows 900 ops/h. These numbers set the thermal cycling limit for the coil and arc chamber, not the mechanical armature. Auxiliary contact ratings: 6 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.8 A at 440 V. These are the make/break limits for the control circuit — useful for interlocking or PLC input circuits. The 230 V rating is given as 20 hp, which aligns with a typical motor load for this contactor size.
Wiring and panel integration
Solid wire accepted: 2.5 to 16 mm²; stranded: 6 to 70 mm². The screw terminals accept two conductors per clamp for daisy-chaining: 2x (0.5 to 1.5 mm²) solid or stranded, or 2x (0.75 to 2.5 mm²). Dimensions: 70 mm wide, 140 mm high, 195 mm deep. The depth is the critical clearance dimension for enclosure depth.
