Type: MPR20


91,3 mm

The MPR20 is a monostable electro-mechanical power relay. Its integral electronic control circuitry helps reduce power consumption in the holding power by the factor 10 compared to standard power relays. It can both switch and carry 300 A. In the event of a power disruption, the relay will at once go into its original state due to its monostable design. This provides more safety and reliability. Reduction of holding power and of the pull-in power allows direct connection to the controlgear and provides additional cost reduction and environmental advantages despite a monostable design. By using standard termination technologies and mounting dimensions, the MPR20 can easily and quickly replace conventional relays.

  • Reduced fuel consumption and CO2 emission due to an 90 % lower holding power
  • Flexible installation for demanding applications due to a robust, waterproof and dust-proof design
  • Reduced installation time through direct connection to the controlgear
