The 45 mm width and 102 mm height match the S0 footprint, with a depth of 107 mm.
Duty Ratings and Switching Cycles
This contactor is rated for different utilization categories: AC-1 at 1,000 operating cycles per hour, AC-2 and AC-3 at 750 cycles per hour, and AC-4 at 250 cycles per hour. The AC-3 rating covers standard squirrel-cage motor switching — the most common motor load in industrial panels. The AC-4 rating, for reversing or inching duty, is lower at 250 cycles per hour, reflecting the increased electrical wear from making and breaking stalled rotor current. The auxiliary switch is included, which simplifies ordering for applications needing status feedback.
Coil and Auxiliary Contact Ratings
The coil draws an inrush peak of 25 A and holds at a lower sealed current. Operating times are 30-50 ms on AC and 30-45 ms on DC. The auxiliary contacts are rated at 10 A at 24 V, 2 A at 48 V and 60 V, and 1 A at 110 V. These ratings determine the signal-level switching capability for PLC inputs or indicator lamps in the control circuit.
Environmental and Mechanical Life
The mechanical life is typically 10,000,000 operations. Conductor sizes accepted: solid or stranded 1-10 mm² for main contacts, and 2x (0.5-2.5 mm²) for auxiliary contacts.
