Earth Fault Relay EF 18 0.1-2A, AC 220/240V 50/60Hz
The EF 18 Earth Fault Relay is a protective device designed to detect and monitor earth faults in electrical systems. It provides reliable protection by detecting leakage currents that may occur when an electrical fault causes a current to flow to the earth. The EF 18 is equipped with adjustable sensitivity settings, ranging from 0.1A to 2A, to ensure precise fault detection and protection for various applications.
This EF 18 Earth Fault Relay operates with AC supply voltages of 220/240V at 50/60Hz, making it ideal for industrial and commercial installations. It ensures safety by immediately triggering an alarm or disconnecting the system upon detection of an earth fault, preventing potential damage to electrical equipment and minimizing safety hazards.
The EF 18 model is particularly useful in systems where leakage currents need to be controlled or monitored, such as in industrial machinery, electrical distribution panels, and other high-power systems.
