GE SR750-P5-G5-S5-LO-A20-R-T Feeder Protection Relay Module

Engineered for precision power distribution management, the GE SR750-P5-G5-S5-LO-A20-R-T serves as a critical component in protecting industrial electrical systems. This relay module combines robust protection algorithms with advanced communication capabilities, making it particularly effective in safeguarding transformers, motors, and distribution lines against overcurrent, earth faults, and voltage anomalies.

Real-World Applications

We’ve seen this particular SR750 variant excel in energy-intensive environments. A mining operation in Chile recently deployed these modules to protect their 13.8kV distribution lines – they specifically appreciated the low control power consumption (LO designation) reducing their backup battery requirements. The Modbus RTU integration with their existing SCADA system took just 2 hours, which is significantly faster than older relay models.

Our inventory includes compatible GE components like the VMIVME-7807 processor modules for system integration, IS230SRTDH2A communication interfaces, and SR469-P5-HI-A20 protection relays for complementary system upgrades. For retrofitting projects, we often pair these with legacy IC698CPE010 processors to maintain backward compatibility while upgrading protection schemes.

Why Choose Abbyes?

While GE discontinued direct support for many SR750 components in 2020, our global network maintains over 400 units in active inventory across 6 regional warehouses. Every unit undergoes 48-hour burn-in testing before shipment, and we offer a full 12-month warranty – longer than the standard 9 months industry norm.
