Switching Duty and Contact Ratings
The contactor is rated for 1,000 operations per hour under AC-1, AC-2, AC-3, and AC-3e duty, and 300 ops/h under AC-4. AC-3 is the standard motor-switching category; AC-4 covers inching and plugging where the contacts make and break stalled-rotor current. The 1,000 ops/h ceiling means this contactor is sized for normal process cycling, not high-speed indexing. Auxiliary contact ratings are given at several DC voltage levels: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. These are the DC-13 switching limits for the auxiliary contacts — important when driving DC relays or PLC inputs from the same block.
Environmental and Timing Specifications
Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C. The storage limit governs handling during transport and off-season storage, not running conditions. Arcing time is 10 to 10 ms, and DC dropout time is 15 to 17.5 ms — these matter for coordination with upstream short-circuit protection and for timing interlock circuits. Wire range for main and auxiliary circuits: solid or stranded 1 to 10 mm², with a dual-wire capacity of 2x (0.5 to 2.5 mm²). The spring terminals accept ferruled stranded wire; strip length should follow the manufacturer's recommendation for spring-clamp terminations.
