About the 750-P5-G5-S5-HI-A20-R-E-H

The 750-P5-G5-S5-HI-A20-R-E-H is one of several digital relays from General Electric’s 750/760 Feeder Protection System line available here at AX Control.   These units are designed to make electrical connections to external equipment while providing protection and control of distribution feeders.    Units like this one are designed for mounting as a solitary unit or they can be mounted in conjunction with other SR series relay units using a standard 19-inch panel rack. 

The 750-P5-G5-S5-HI-A20-R-E-H has 5 amp phase current inputs.  It is designed with 5 amp zero-sequence current inputs and 5 amp sensitive ground current inputs.  There are eight 4-20 mA analog outputs located on the unit.   The 750-P5-G5-S5-HI-A20-R-E-H uses an 88-300 VDC 70-265 VAC @48-62 Hz power supply.   It is rated for use within harsh chemical environments. 

The 750-P5-G5-S5-HI-A20-R-E-H offers a number of standard features and benefits.  These include automatic bus transfer and synchro check (V, f, Hz, and dead source), reverse power protection, and restricted Earth Fault protection.   The unit has several networking interfaces including Ethernet,  RS232, RS485, and RS422 ports that can handle protocols like Modbus RTU, TCP/IP, and DNP 3.0. 

Control/Communications can be local or remote.  Local control is offered using the LCD panel and associated keypad and control keys.  Contact and serial inputs can be programmed for remote tripping, feature blocking, or resetting.  Rear ports allow connections to a distributed control system, PLC, or SCADA system. 

Additional information including FAQs, wiring diagrams, guideform specs, and application notes can be sourced through the OEM.  This information will help guide you safely through installation, maintenance, and all handling.
