Power contactor 20 A | HS 20-20

electromagnetic

Installation contactors are electromagnetically operated switches. If a control current flows through the magnetic coil, the main circuit closes the magnetic energiser. As long as the control current flows, the switch-on position is maintained. If the control current is interrupted, a spring forces the disconnection o return of the contacts to their original position. This design means that contactors ensure a galvanic separation between the control circuit and the switched circuit whilst simultaneously allowing high currents to be switched. Installation contactors are only designed in a limited way for release and must be protected against overload and short-circuits by upstream protective devices. Installation contactors in series HS for installation in distribution boards are extremely quiet and have very low-noise switching processes, are highly versatile thanks to their utilization categories and have a long mechanical and electrical service life. The magnetic coil of this series is suitable for continuous operation (100% duty cycle). Devices in this design are operated with a control voltage of 230 V AC. Features: available control voltages 24 V AC and 230 V AC, rated currents up to 63 A, wide range of different contacts, high electrical and mechanical endurance, extremely quiet, suitable auxiliary switch and seal cap available
