The Most Energy-Efficient Monostable Power Relay

The MPR20 is a monostable electro-mechanical high current relay. Its wide range input allows installation and operation in both 12V and 24V on-board electrical systems without change of the hardware and it carries 300A continuously. In the event of a power disruption, the relay will at once go into its original state due to its monostable design.

Reduction of holding power by 80% and of pull-in power by 50% allows direct connection to the controlgear and provides additional cost reduction and environmental advantages in spite of a monostable design. By using standard termination technologies and mounting dimensions, the MPR20 can easily and quickly replace conventional relays.

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