Contactors, also known as commutation devices with solenoid actuator, are used for the manipulation of electrical networks and associated with them users from a distance.
They function on the relay principle, but the technical parameters that operate are much larger than those of conventional relays.
Their values can reach from several amperes to a hundred amperes and several kV voltage. When used in a combination with thermal relays, contactors are used to protect the electrical system from overload.
AC-1- a mode with active or lightly inductive load.
AC-3- a mode with direct involvement of motor with a squirrel cage rotor.
AC-4- starting of a motor with squirrel cage rotor, operating in the short-term and repeating short-term with a sharp start and stop.
Vikiwat Ltd. is a direct importer of a complete range of contactors and protection relays with high quality and competitive prices.
