Hotline : 0976 33 55 58

Intuitive and innovative feeder protection system

The Multilin™ 350 is a member of the Multilin 3 Series protective relay platform and has been designed for the protection, control and management of feeders or related applications as a primary or backup protection device. This cost-effective protective device is used to perform advanced feeder protection, control and monitoring for low, medium and high voltage applications. The 350 also offers enhanced features such as integrated arc flash protection, metering, monitoring and diagnostics, preventative maintenance, advanced communications and security.

The 350 protection relay chassis used with a draw out relay is available separately, for use as a partial replacement or in test environments. The draw out relay with no chassis is also available to order as a spare unit.
