A compact fail-safe Type A earth leakage relay for use with an external BZCT toroid, providing true RMS detection of AC and pulsating DC residual currents. Its output relay is normally energised and de-energises on trip or loss of supply, while adjustable sensitivity and time delay allow the protection to be matched to the installation.
