It is rated for a mechanical life of 30,000,000 operating cycles typical, and carries auxiliary contacts rated at 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 3 A at 400 V, and 0.14 A at 440 V. The main contact range is 20 to 12 mm², and the unit accepts solid or stranded wire from 0.5 to 4 mm², including dual conductors of the same size.
Switching frequency and arcing
Maximum switching frequency depends on duty: AC-1 at 1,000 cycles/h, AC-2 and AC-3 at 750 cycles/h, AC-3e at 750 cycles/h, and AC-4 at 250 cycles/h.
