GE VERNOVA | DISTRIBUTION & INDUSTRY FEEDER PROTECTION SYSTEM | MULTILIN 350

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.

Key Features

Front USB and rear serial, Ethernet, fiber and dual port options for seamless redundancy (IEC 62439-3, PRP & HSR)
Multiple communication protocols supporting industry leading standards

Advanced Communications

The 350 incorporates the latest communication technologies, making it the easiest and the most flexible feeder protection relay for use and integration into new and existing infrastructures. The 350 relay provides the user with one front USB and one rear RS485 communication port. Also available with the 350 is a rear communication port with Ethernet Fiber and Copper. For configurations requiring PRP and HSR redundancy protocols, the 350 provides two rear Fiber ports. Through the use of these ports, continuous monitoring and control from a remote computer, SCADA system or PLC is possible.

The 350 provides optional Parallel Redundancy Protocol (PRP) and High Availability Seamless Ring (HSR) according to the IEC 62439-3 standard that defines two protocols to increase network availability by reducing failover time to zero. Both ports are capable of simultaneously supporting the following protocols: Modbus TCP/ IP, IEC 61850, DNP3 or IEC 60870-5-104, IEEE 1588, SNTP and OPC-UA.

Link Loss Alert (LLA) function detects any issue with one port and switch to the other one in case of failure.

The 350 supports popular industry-leading standard protocols enabling easy, direct integration into electrical SCADA and HMI systems. The protocols supported by the 350 include,
