The coil terminals use spring-type connections, so you land the control wiring without a screwdriver — speeds up panel build and avoids loose terminations on a vibrating line.
The 20-12 A main contact range covers the AC-3 motor switching duty for fractional-horsepower loads. The 1 hp rating at 230 V tells you it handles a typical small motor on a 230 V single-phase supply — common on packaging lines for infeed belts or label applicators. Switching frequency limits are per duty class: up to 1000 cycles/hour in AC-1 (resistive), 750 in AC-3 (motor start/run), and 250 in AC-4 (plugging/inching). If your application does frequent reversing or jogging, the AC-4 limit governs — don't exceed 250 operations per hour.
The Size S00 footprint — 45 mm wide, 70 mm tall, 73 mm deep — fits standard panel layout grids. Wire range accepts 0.5 to 4 mm² solid or stranded, or 2x (0.5 to 4 mm²) for looping through.
Auxiliary contacts and coil data
An integrated auxiliary switch is standard — no add-on block needed for basic status feedback. Auxiliary contact ratings vary by voltage: 10 A at 24 V, 2 A at 48/60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, 0.2 A at 440 V. Operating time is 4-15 ms AC; arcing time is 10-15 ms. Mechanical service life is typically 30 million operations.
