Rated at 5.5 kW at 400 V in AC-2 duty (slip-ring motor starting) and 8.5 A in AC-4 duty (plugging/inching), this contactor handles moderate motor loads common in conveyor and pump applications. The AC-2 figure tells you the continuous motor-switching capacity; the AC-4 figure governs the inching and reversing cycles where contact wear is higher. Main contact ratings span 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, and 5.5 kW at 690 V, giving you a quick check for resistive or lightly inductive circuits at different line voltages. The 690 V rating (5.5 kW) matches the same power as the 400 V AC-2 rating, confirming the contactor is sized for the motor load, not just the line voltage.
Coordination and wiring
These fuse specs are what you hand to the panel builder for the branch circuit design. Screw terminals accept 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) solid or stranded wire, and 1x 12 AWG. The dual-wire entry is handy for daisy-chaining control wiring without extra terminal blocks.
Mechanical fit and environment
The S00 frame measures 45 mm wide, 57.5 mm high, and 72 mm deep — a compact footprint that leaves room for auxiliary contact blocks or other devices on the same DIN rail.
