Description
The PSE142-600-70 is a high-performance protection relay designed by ABB for medium-voltage power distribution systems, delivering reliable fault detection and control in industrial, utility, and renewable energy applications. As part of ABB’s REL670 series, this relay combines advanced protection algorithms with modular scalability, ensuring robust performance in harsh environments.
The
PSE142-600-70 safeguards critical equipment such as transformers, feeders, and motors from overcurrent, earth faults, and short circuits. Its
dual-core processing and
IEC 61850 communication enable real-time monitoring and seamless integration with smart grids. With
24–48 V DC/AC operation and a
-25°C to +70°C temperature range, the relay thrives in extreme conditions, minimizing downtime and operational costs.
