Contact Ratings and Switching Capability
The 4 NO contacts carry different currents depending on the switching voltage — a key detail for control transformers or PLC input isolation. At 24 V the rated operational current is 10 A; at 60 V it drops to 4.7 A; at 110 V it is 3 A; at 220 V it is 1.2 A; at 230 V it is 6 A; at 400 V it is 3 A; at 440 V it is 0.5 A; at 500 V it is 2 A; at 600 V it is 0.26 A; and at 690 V it is 1 A. These are not all the same curve — the 230 V and 400 V figures are higher than the 220 V and 440 V ones, so verify your actual control voltage against the correct row. Mechanical endurance is listed at 10 million operating cycles typical, with a maximum switching frequency of 10,000 operations per hour at AC. The arcing time is 10 to 15 ms, and the DC switching time is 7 to 13 ms. For inductive DC loads, the varistor helps clip the voltage spike, but the lower current ratings at higher DC voltages (e.g., 0.26 A at 600 V) reflect the real arc-quenching limit.
Physical Integration and Wiring
The contactor measures 45 mm wide, 57.5 mm tall, and 117 mm deep — the depth is the dimension that extends into the enclosure, so check your cabinet depth against that 117 mm plus wiring clearance. Clearances to grounded parts: 10 mm upwards, 10 mm forwards, 10 mm downwards, and 6 mm at the sides. Terminals accept solid or stranded copper: 2x (0.5 to 1.5 mm²), 2x (0.75 to 2.5 mm²), or 2x 4 mm². The closing power of the magnet coil at DC is 4 W. Operating temperature range is -25 to +60 °C; storage range is -55 to +80 °C.
