Advanced Numerical Protection

The MICOM P143 is engineered to safeguard electrical systems through a suite of protection features including distance, overcurrent, earth fault, and breaker failure protection. Its microprocessor-based architecture ensures precision, speed, and adaptability, making it suitable for both new installations and upgrades. Reliable operation is assured by automated testing during startup and runtime.


Versatile Communication and Configuration

Designed for modern substations, this relay supports multiple communication protocols-IEC 60870-5-103, Modbus, and DNP3-across RS232, RS485, and fibre optic ports. Local operation is facilitated by a graphical LCD and keypad, while both digital and analog inputs allow extensive application. Outputs are programmable for trip, alarm, and more.


Rugged Construction and Easy Maintenance

Built to endure challenging environments, the MICOM P143 relay operates efficiently in temperatures ranging from -25C to +70C. Its robust flush-panel mount casing, high insulation resistance, and plug-in removable terminal blocks simplify installation, troubleshooting, and maintenance. Firmware can be upgraded via the front port or network.
