Product details

Coil and auxiliary contact ratings

The DC coil dropout delay is 80 to 100 ms, which matters for sequencing logic where you need to know how long the main poles hold after control power drops. The auxiliary switch is rated at 6 A at 24 V DC, 2 A at 48 V DC, 2 A at 60 V DC, 1 A at 110 V DC, and 0.9 A at 125 V DC — these are the DC-13 switching limits for the built-in contact, not the main pole ratings. Verify your auxiliary load against these curves before committing the BOM line.

Duty cycle and thermal limits

Maximum operating cycles per hour vary by duty: 500/h for AC-1, AC-3, and AC-3e; 200/h for AC-2; 130/h for AC-4; 250/h for DC-1, DC-3, and DC-5.

Screw fixing with one 11 mm diameter hole. Accepts solid or stranded wire: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), max 2x (0.75 to 4 mm²). Dimensions: 225 mm depth, 160 mm width, 214 mm height.
