Product Description

The GE Multilin 735-5-5-HI-485 (also referred to as SR-735-5-5-HI-485) is a robust, microprocessor-based feeder protection relay designed for the comprehensive management of electrical distribution systems. As part of the standard 735 series, this unit integrates essential protection elements, including phase overcurrent (50/51) and ground overcurrent (50G/51G) functions. It is engineered to safeguard critical electrical assets in substations, switchgear, and industrial power monitoring systems by providing high-speed fault detection and trip signaling.

Equipped with a high-voltage (HI) power supply, the 735-5-5-HI-485 operates reliably across a wide range of AC and DC inputs, making it adaptable to various station battery or auxiliary power configurations. The inclusion of an RS485 2-wire communication port allows for seamless integration into SCADA systems and power monitoring networks via the Modbus RTU protocol, enabling remote monitoring of electrical parameters and relay status.
