At 500 V it handles 30 kW, and at 690 V it's rated 11.4 kW.
The AC-3 maximum switching frequency is 800 cycles per hour — that's the mechanical endurance limit for standard induction motor starting. AC-4 drops to 300 cycles per hour, reflecting the heavier duty of plugging or inching. If your application cycles faster than these numbers, the contactor will overheat or wear prematurely. The auxiliary contact ratings at 24 V DC are 10 A, dropping to 0.3 A at 220 V DC. For DC control circuits, check the voltage-specific rating — the 24 V figure is generous, but at higher DC voltages the current capability falls off sharply due to arc extinction limits.
Side-by-side mounting is permitted — no derating required for adjacent units, which simplifies panel layout. The Size S2 footprint is 55 mm wide, 112 mm high, 115 mm deep. Main circuit terminals accept solid wire from 2x 0.5 mm² up to 2x 4 mm², or stranded from 2x 0.75 mm² up to 2x 25 mm². That range covers most motor feeder cables up to about 6 AWG. The front face is IP20 — safe for finger contact in an enclosed panel.
