The Hager 4Pole Earth Leakage Circuit is a four-pole residual current device (RCD) designed to protect people and property by quickly detecting imbalances between live conductors and the neutral/earth. When a fault current is detected, it trips the circuit to cut off electricity, helping prevent electrocution and electrical fires in 3‑phase installations.

For further details, check the product page on Fepy (the main listing for this Hager 4Pole Earth Leakage Circuit) and the linked documentation or support sections. If you need tailored guidance, you can reach out to Fepy support or consult an electrical professional to ensure correct application and installation.

Key specs to compare include the number of poles (4), leakage current sensitivity (mA, e.g., 30mA), current rating (A), type/class (e.g., Type AC), presence of an integrated status display, and reset/test functionality. Also check panel compatibility and mounting style to ensure it fits your enclosure.

RCDs like the 4Pole earth leakage circuit have long service lifespans with periodic electrical testing. Maintenance mainly involves regular test and reset checks, ensuring clean connections, and replacing the unit if the device shows signs of wear, drift in trip levels, or repeated nuisance trips suggestively indicating a fault.

Consider factors such as the current rating (amperes), leakage sensitivity (mA), installation environment, panel compatibility, and total cost of ownership. If your system requires higher current handling, a 63A variant might be preferable; for lower-leakage sensitivity, a 30mA option may be suitable. Always verify compatibility with your existing panel and wiring.

Use the integrated test button to simulate a leakage fault and verify that the device trips as expected. After a trip, reset the circuit using the reset control once the fault condition has been cleared and it is safe to restore power. Regular testing helps ensure ongoing protection.

Always follow local electrical codes and standards. Use the device only in appropriate panels and environments, ensure proper insulation and enclosure, and perform periodic testing using the built-in test function to confirm reliable operation. If in doubt, consult a qualified electrician.

It is well-suited for commercial and industrial environments with 3‑phase power, as well as large residential installations that require comprehensive earth leakage protection. It protects people from electric shocks and helps safeguard equipment and property from leakage faults.

Installation should be performed by a qualified electrician. The device is intended for 3‑phase systems with a neutral. Connect the incoming supply to the line terminals, the outgoing circuits to the load terminals, and ensure correct phase alignment. After wiring, use the reset and test features to verify proper operation and restore power only after confirming safe connections.

The integrated display provides at-a-glance status of the protection system, including the current limit setting in milliamps (mA) and warnings if the limit is exceeded. A visible indicator helps you quickly verify that protection is active and within safe parameters.

It uses intelligent sensing to monitor voltages and currents and looks for deviations from preset levels. The device maintains multiple levels of protection to detect low-level leakage currents quickly while resisting nuisance trips from transients or interference. When a fault is detected, it trips the circuit and disconnects power.
