It carries an auxiliary switch and uses spring-type terminals for the magnet coil — no screw tightening needed on that circuit.
Coil and switching specs
Coil inrush peaks at 6.5 A; steady-state draw at 50/60 Hz is 3.5 VA. The coil operates on a 20... 33 V supply. Switching times are symmetrical: both make and break fall in the 38... 57 ms range at AC and DC, with arcing lasting 10... 20 ms.
Duty cycle and contact ratings
The contactor is rated for AC-3 motor duty at up to 850 switching cycles per hour (also rated AC-3e at the same figure). For heavy AC-4 jogging/reversing duty, the rate drops to 200 1/h; AC-1 resistive loads allow 900 1/h. Auxiliary contacts are present — the main contact count is listed as 10... 2, which typically means three normally-open and one normally-closed main poles plus the auxiliary block, though the exact configuration should be cross-checked against the full order-code suffix.
The S3 frame measures 70 mm wide by 140 mm high by 198 mm deep.
Wire sizes and environment
Main power terminals accept solid wire from 2.5 to 16 mm² and stranded from 6 to 70 mm². Auxiliary/control terminals take 2x (0.5... 2.5 mm²) solid or stranded. The contactor is rated for 10 million typical mechanical operations.
