GE B30TG3HLHFXXH

Product Overview

The GE B30TG3HLHFXXH is a Multilin B30 bus differential protection relay designed for electrical power system protection and control. It is part of GE's Universal Relay (UR) family and provides reliable monitoring and protection for busbar systems in industrial substations and power generation facilities.

The relay continuously evaluates electrical measurements from connected circuits to identify abnormal operating conditions. When a busbar fault is detected, it can initiate the appropriate protection and circuit breaker tripping actions to help minimize equipment damage and maintain system stability.
