Protection Relays & Systems are a vital part of any power system, providing its users with relief against power distribution failure. The PGR-4300-12 is a protection relay specifically designed to detect power faults and trigger immediate mitigation in the form of automatic switching off and on of system components.

The PGR-4300-12 features one-shot pickup and single-shot trip plate, providing short-circuit protection for main feeder cables, lines, transformers and other electrical equipment. Its user-friendly operation panel also offers powerful yet intuitive functions such as local/remote operation, trip limitation selection, overloads and earth faults.

The PGR-4300-12 is designed for applications such as substations, distribution centers, power plants and factories. It is an ideal choice for any medium voltage system where fault protection is needed. The device\'s overload protection can be used to protect equipment prone to overheating, reducing the chances of component damage and ultimately extending the system\'s lifespan.

In terms of working principle, the PGR-4300-12 uses advanced circuit-measuring algorithms to detect and interrupt AC power current. The device\'s current transformer (CT) is supplied through a transformer with a fixed current ratio. When a given fault threshold is exceeded, the relay provides a trip signal to initiate the disconnection by opening the circuit breaker. The single-shot trip plate allows for repeat trips to diagnose and clear faults.

The PGR-4300-12 is designed for optimal installation and maintenance. The device\'s modular design makes it easy to integrate with other components without compromising safety. Its self-checking feature allows it to detect problems with its internal components, and if necessary, activate an alarm. This ensures that sensitive electrical equipment is not damaged beyond repair.

Overall, the PGR-4300-12 is a reliable and cost-effective protection relay offering a powerful set of features for medium-voltage systems. Its efficient operation provides users with greater peace of mind. And its modular design offers users easier installation and maintenance.
