Elr 4md Dc Digital Earth Leakage Relay - China
price: 180.00 Dollar US$
The ELR-4MD DC Earth Leakage Relay is an advanced protection device designed to enhance the safety and reliability of electrical systems.
With a hall effect current sensor (HCT), it continuously monitors the residual current in the busbars or branches of the DC system.
When the residual current exceeds the preset threshold, the relay promptly outputs an alarm signal, ensuring early detection of potential faults.
Equipped with an alarm function, the ELR-4MD DC digital earth leakage relay ensures that alarm signals remain clearly indicated until received the reset signal, facilitating easy fault diagnosis and troubleshooting.
ELR-4MD DC earth leakage protection relay is critical for preventing equipment damage, minimizing downtime, and safeguarding personnel against electrical hazards.
