Industrial gear runs forever, and this one's still rolling off the line, so you're getting the same guts that have pulled decades in thousands of panels. It switches motor loads at AC-3 duty up to 750 cycles per hour, and can handle AC-4 jogging at 250 cycles per hour. For straight resistive loads (AC-1) it does 1 000 ops/h.
Mounting and mechanical fit
Physical envelope: 85 mm high x 45 mm wide x 97 mm deep. When ganging contactors side by side, maintain 6 mm clearance on the sides. For vertical spacing above/below, 10 mm each way. That's enough for airflow and wiring access with the screw terminals. Main contact wiring accepts 1 x 1 … 10 mm² solid or stranded (fine strand same range). Auxiliary terminals take 2 x (0.5 … 1.5 mm²) or 2 x (0.75 … 2.5 mm²) – typical for control wiring.
