Product Overview

The 735-5-5-HI-485 (Part Number: SR-735-5-5-HI-485) is a microprocessor-based protective relay engineered for the comprehensive management and protection of electrical distribution feeders. As a cornerstone of the GE Multilin 735 series, this unit provides specialized protection against phase and ground overcurrent conditions. It is designed to be integrated into substation switchgear and industrial power systems, ensuring high-speed fault detection and reliable trip execution to prevent catastrophic equipment failure.

Equipped with the "HI" high-voltage power supply, the 735-5-5-HI-485 (Model: 735-5-5-HI-485) maintains stable operation across a broad range of station battery voltages and auxiliary AC sources. The integration of a dedicated RS485 communication port enables this relay to function as an intelligent electronic device (IED) within a broader SCADA architecture, providing real-time metering data and event records via the Modbus RTU protocol.
