TeSys F magnetic latching contactor, 3 poles (3NO), 150A/1000V AC-3, for motor applications up to 75kW@400V. It provides a double coil 110V AC (50-400Hz) or DC for latching and unlatching, bolt terminals for bars or cables with lugs. Supply to the coils must be applied by pulsed contacts leading to energy saving and no sensibility to interferences for contactors remaining in closed state for long periods. For operating rates until 120 cycles/hour and environments until 70°C, it procures high reliability and durability. It makes installation and maintenance easy thanks to its drawer-mounted coil and a large choice of add-on blocks (instantaneous and time delay auxiliary contacts, suppressor blocks) and connection accessories (to be ordered separately). It conforms to IEC 60158-1 and IEC 60947-4.
