It carries a mechanical life of 10 million operations and supports up to 700 switching cycles per hour under AC-1 duty, 500 per hour under AC-3. Rated for operation from -25 to +60 °C and storage from -55 to +80 °C, it fits a 114 x 55 x 130 mm envelope and mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715.
Mounting and fit
Clearance requirements: 10 mm upward, 10 mm downward, 10 mm forward, 10 mm rearward, and 6 mm to the side.
For high-cycle applications, note the maximum operating frequency: AC-1 resistive loads 700 cycles/h, AC-2 slip-ring motors 350/h, AC-3 squirrel-cage motors 500/h, AC-4 plugging/inching 150/h.
