Earth Leakage Protection Relay

Earth Leakage Protection Relay

Residual current devices are used to detect dangerous ground fault currents before damage is caused to expensive power assets.

The ELRP/S monitors the earth leakage current and compares it with the user selectable trip level. Should this level be exceeded, the relay will trip and with a response time of under 40ms, the supply can be disconnected before serious damage can occur.

• Continuous monitoring of the current value using an external current transformer
• Response time (<40ms) • Adjustable trip current settings
• Adjustable time delay set point • Selectable pre-alarm relay functions - ELRP or ELRS
• For each function the relay state in case of failure may be set - ON or OFF
• RESET & TEST button for the return to the initial state or device test
• Analogue output 0...1mA for the control meter
