ezPAC SA300

The SATEC ezPAC SA300 is a multifunction protection, control, and PQ analyzer designed for MV feeders and industrial distribution networks. It integrates feeder protection (overcurrent, earth fault, directional), monitoring, PQ analysis, and SCADA communication into a single compact device. Supporting IEC 61850, GOOSE, and high-speed Ethernet, the SA300 is suitable for digital substations and automation systems. The device includes high-resolution waveform and disturbance recording, harmonic analysis, and event logging for accurate fault investigation. With programmable logic and flexible I/O, the SA300 enables local automation, breaker control, and condition monitoring. Its rugged hardware ensures stable operation in harsh MV switchgear environments.
