Schneider Electric Easergy MiCOM P433 Distance Protection Relay

Schneider Electric Easergy MiCOM P433 Distance Protection Relay is designed to protect medium-voltage and high-voltage transmission and distribution networks against short circuits, earth faults and overload conditions. It combines high-speed distance protection with control and monitoring functions, making it suitable for substations where dependable fault clearance and operational control are equally important.

The relay uses advanced distance protection algorithms to identify and locate faults quickly, helping reduce outage time and limit the impact on the electrical network. In addition to protection, the MiCOM P433 supports switchgear control, allowing operators to monitor and operate equipment from a single relay platform.

The modular design makes the relay suitable for both new substations and retrofit projects. With flexible input and output options, communication interfaces and support for substation automation, the MiCOM P433 can be integrated into modern protection and control systems with minimal effort.
