GE Multilin SR760 760-P1-G1-S1-HI-A20-R is the autoreclose version of the 750/760 feeder-management platform, configured for 1 A phase, zero-sequence and sensitive-ground sources. Its HI supply accepts a broad ac/dc range, while the A20 option provides eight analog transducer outputs for control-room or plant-interface use.
- SR760 feeder protection with autoreclose
- P1, G1 and S1 one-ampere current-input options
- HI wide-range ac/dc control power
- Eight A20 4–20 mA analog outputs
The operating chain runs from Phase, ground and sensitive-ground CT circuits → SR760 measurement and protection elements → Trip / reclose control logic → Breaker, alarms and eight analog outputs; document each boundary and prove the intended final response before release.
Important Notice: Treat P1, G1, S1, HI, A20 and R as functional ordering selections; do not replace the relay from the SR760 family name alone.

GE SR760 760-P1-G1-S1-HI-A20-R Official Technical Reference Excerpt (PDF)GE SR760 760-P1-G1-S1-HI-A20-R Installation & Commissioning Guide (PDF)
The Official Technical Reference Excerpt retains the applicable GE Multilin ordering-code and manual-change pages for the configured SR760 relay. The independent commissioning guide covers CT safety, auxiliary power, settings restoration, trip/reclose tests and analog-output acceptance.
Feeder protection
Applies coordinated phase and ground protection to medium-voltage feeders.
Automatic reclosing
Supervises breaker trip and programmed reclose sequences.
Sensitive ground detection
Uses the S1 one-ampere input for low-level ground-fault measurement.
Plant analog integration
Transmits selected measurements over eight 4–20 mA output channels.
Apply these controls specifically to GE SR760 760-P1-G1-S1-HI-A20-R before isolation, replacement, reconnection, energization and final release.
1
Short and isolate CT secondary circuits before disconnecting GE SR760 760-P1-G1-S1-HI-A20-R.
2
Confirm all phase, zero-sequence and sensitive-ground sources are 1 A secondary circuits.
3
Verify the HI auxiliary supply is within the stated ac or dc range before energization.
4
Back up settings, logic, relay assignments, reclose sequence and calibration data before replacement.
5
Maintain CT polarity and phase order when reconnecting P1, G1 and S1 inputs.
6
Scale each A20 channel for 4–20 mA operation at the receiving system before loop testing.
7
Block breaker operation during secondary-injection and output-relay tests unless the approved plan requires movement.
8
Complete protection, trip, reclose, metering, LED and analog-output tests before service release.
Technical notes
Confirm each order-code segment against the relay label, CT secondary ratings, auxiliary supply, analog-output wiring and breaker indication. Restore the approved settings file and test protection, trip, reclose and all eight 4-20 mA outputs before service.
