Replace multiple single-function protection relays with this ground-breaking multi-functional protection relay. Quickly configured using DEIF’s unique PC tool, the MTR-4P makes for a cost-effective and extremely flexible alternative to traditional solutions!

The MTR-4P is ideal for both stand-alone protection or as part of single-/three-phased power networks requiring marine approval.

Being fast, simple and multi-functional, the programmable MTR-4P relay offers up to 13 different protection functions in six different logical categories: Voltage, current, frequency, asymmetry, load and loss of Mains (LoM). Replacing 5-10 single-function protection relays is a seamless procedure!
