GE C60TG3HLH Breaker Protection and Control Relay

Product Description

The GE Multilin C60TG3HLH is a high-performance breaker protection and control relay, engineered for dual‑breaker busbar systems including breaker‑and‑a‑half and ring bus configurations. It ensures reliable operation under fault conditions, fast breaker coordination, and seamless integration with modern SCADA and DCS networks. Moreover, its modular design simplifies installation and maintenance, making it ideal for both new and retrofit substation projects.

With integrated protection functions such as breaker failure protection, reclosing, synchronism check, and continuous breaker monitoring, the C60TG3HLH offers comprehensive fault management. Its programmable logic executes with high determinism, allowing precise automation and rapid fault isolation. In addition, the relay supports extensive digital inputs and high-speed output relays, ensuring versatile configuration for complex substation layouts.

Engineered for industrial and utility environments, this relay is substation-hardened and designed to withstand demanding operational conditions. It provides real-time monitoring, configurable alarms, and robust communication protocols, enabling operators to maintain system reliability and optimize power distribution. Furthermore, its flexible control power options and CT/VT compatibility allow deployment in diverse voltage and current setups.
