Feeder protection
Provides overcurrent and earth-fault protection for feeders. See the MPR selection table for the full set of functions and interface options.
← Products
MPR SERIES
MPR-2013
Feeder protection and control
Integrates protection, measurement, monitoring and control for feeder circuits.
Product features
Measurement, control and recording
Combines current and voltage inputs, status monitoring and relay control with disturbance recording, setting-group switching and programmable outputs.
System communications
Supports RS485 / Modbus RTU and CANBUS / IEC 60870-5-103, with an optional Ethernet interface.
Where it fits and why
Combine feeder protection, breaker status, control and recording, then match the communications interface to the network.
Feeder vs. overcurrent protection
MPR-2013
Feeder protection and control with selectable communications interfaces.
MPR-2014
Focused on phase and earth-fault overcurrent, breaker monitoring and RS485.
