Features:
- Five-ampere phase and ground-current inputs feed feeder protection, metering and fault-location functions.
- Eight 4–20 mA outputs export selected measured or calculated quantities to plant systems.
- Three serial ports support Modbus RTU, with DNP 3.0 available on a configured rear path.
The present order identity combines the P5, G5, D5, HI, A20 and R hardware choices in a legacy SR-family drawout case.
Protection elements process CT and voltage quantities, operate breaker logic and record disturbances for event analysis and maintenance.
For either spare replacement or 850 migration, preserve the settings, logic equations, I/O map, terminal blocks and time-synchronization design.

- Distribution feeders can use directional and nondirectional overcurrent elements for primary protection and breaker tripping.
- Industrial switchgear can implement bus interlocking, source transfer and load-shedding schemes with relay logic and I/O.
- Protection teams can analyze stored events, fault location and waveform captures after a trip without a separate recorder.
- Serial communication and analog outputs transfer relay data to plant control and monitoring systems.
- Feeder protection, breaker control, metering and event information are combined in one drawout relay assembly.
- Five-ampere phase and ground CT inputs supply the quantities used by overcurrent and ground-fault protection elements.
- Three serial communication ports support local engineering and integration with supervisory or plant-control equipment.
- Modbus RTU and DNP 3.0 are supported, while Ethernet capability depends on the installed communication option.
- The complete suffix set, CT ratios, setting file and breaker logic must be preserved or re-engineered during migration.
- The P5 option provides 5 A phase-current transformer inputs for feeder measurement and phase protection functions.
- The G5 selection uses a 5 A zero-sequence ground-current input for residual or core-balance measurement circuits.
- The D5 option defines the polarized ground-current configuration that works with the selected 5 A ground input.
