It's the switching element for control circuits — think PLC outputs driving contactor coils, signal interlocking, or status feedback back to the controller. The S00 frame is compact — 57.5 mm high, 90 mm wide, 73 mm deep — so it fits in tight enclosure rows without crowding adjacent devices.
Current ratings across the voltage range
This contactor's rated operational current drops as voltage rises — a standard thermal characteristic for auxiliary contacts switching inductive loads. At 24 V it's 10 A; at 110 V it's 3 A; at 230 V it's 10 A (likely AC resistive); at 400 V it's 3 A; at 690 V it's 1 A. The DC curve is steeper: 4.7 A at 60 V, 1.2 A at 220 V, 0.5 A at 440 V, 0.26 A at 600 V. Match your control voltage to the right column — don't assume the 24 V figure holds at 400 V.
Integration notes
Wire termination accepts 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm² solid or stranded. Mechanical endurance typical 5,000,000 cycles.
