VS425 serie contactor is designed for auxiliary and power switching of heavy electrical loads. It is used for switching electrical circuits, especially resistive loads and three-phase asynchronous motors. It switches larger loads, especially in other categories such as AC-1. In IP20 protection, covers are available on request to ensure IP40 protection of all contactor terminals. Universal supply voltage AC/DC 12 - 240 V or AC 230 V. Manufactured with 40, 31, 22, 04 switching and opening contact configurations. Number of contacts: 4. In 2-MODULE design, DIN rail or panel mounting..
The interruption of power supply from the production module is ensured by contactor KM1, which is switched by connecting the N wire to its coil from the distributor control device. Connecting the N wire switches on the contactor and disconnects the production module from the distribution network via its power NC contact.The delayed connection of the production module after a mains failure is ensured by the time relay KA1. After a loss of mains voltage, the relay KA1 galvanically disconnects the production module from the distribution network (breakdown point KM1). When the voltage is restored, relay KA1 reconnects the production module after a set time.
