E-T-A MPR10 Mechanical Power Relay

The Lightest Bistable Power Relay


The MPR10 is a single pole, bistable power relay. It was designed for switching high current loads and for disconnecting the battery from the on-board electrical system.

For the switching operation, the MPR10 only requires a short current pulse. Afterwards, the permanent magnets hold the contact reliably closed at no
load. Materials of superior quality make the MPR10 the lightest water-proof and dust-proof power relay in the market. It offers extremely flexible installation
options in utility vehicles.

A range of mounting versions allows direct replacement of standard relays. The MPR10 can carry or switch up to 300A continuous current at DC 12V and 24V.
