Product Description

ALP220-EF Low-voltage Earth Fault Relay

General

Acrel ALP220-EF Earth Fault Overcurrent Relay is designed for low-voltage applications (up to 380 V) where it is necessary to monitor the system's ground current and provide protection when the ground current exceeds the permissible limit. This relay features an LCD display, Modbus-RTU communication capability, system current measurement, three-phase current overcurrent protection, ground current overcurrent protection, residual current measurement, residual current overcurrent protection, fault logging, and event logging functions.
