It carries a 200 V DC coil with built-in bidirectional peak-limiting diode suppression, so the control circuit is protected from inductive kickback without an external flyback diode. Rated for AC-1 utilisation (resistive loads), it is suited for control applications where the load current is non-inductive — heating elements, lighting banks, or transformer primary switching.
The rated insulation voltage (Ui) is 690 V per IEC 60947-4-1 and 600 V per UL 508 / CSA C22.2 No 14, meaning the contactor can be used in 480 V or 600 V panel designs with adequate clearance. The rated breaking capacity reaches 110 A at 440 V, 80 A at 500 V, and 70 A at 660–690 V — these are the maximum fault currents the contactor can safely interrupt, not the continuous rating. The AC-1 thermal current (Ith) is 20 A at 50 Hz, with an average power-circuit impedance of 3 mOhm, so heat dissipation stays at 3 W under full load — a manageable figure for a DIN-rail enclosure with natural convection.
Mounts on plate or DIN rail, with screw-clamp terminals accepting 1 or 2 conductors from 0.34 to 4 mm² (solid or flexible). Tightening torque is 1.3 N·m using a No. 2 Philips or 6 mm flat-blade screwdriver.
