General purpose auxiliary relays
ARTECHE’s general purpose auxiliary relays are designed to directly operate to the tripping and control circuit. Furthermore, its multiple output contacts permit to use these relays in control, interlocking, timing and signalling applications as well as per direct operation on HV and MV primary equipment.
Auxiliary relays with seismic characteristics
ARTECHE’s auxiliary relays with seismic characteristics are designed to work properly perform under frequent vibration and shock applications, as railway sector, or because of safety requirements as nuclear power plants. The sturdy design of our equipment, with a higher appropriate pressure between contacts, permits to withstand vibrations without penalizing the good performance of the relays.
Auxiliary relays with coil overvoltage protection
ARTECHE’s auxiliary relays, either Vdc or Vac, have the possibility of including an element in parallel with the coil (diode or varistance). In applications with overvoltage, where drop-out time is not important, it is recommended to use diode. Otherwise, varistance is more suitable. These elements are aimed to discharge the energy of the coil when the relay is not longer energized. These relays are indicated when the customer wish to protect the contact of the equipment that commands the operation of our relay, providing a longer durability of the whole protection and control system.
