Hager CE485Z 100A 4Pole 100Ma Earth Leakage Circuit

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.

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.

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.

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.

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.

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.

On Fepy you can compare similar 4Pole RCCBs from Hager and other brands. For example: 1) Hager 4Pole RCCB 40A 30mA Type AC — https://fepy.com/product/hager-4pole-rcb-40a-30ma-type-ac 2) Hager 4Pole RCCB 63A 30mA Type AC — https://fepy.com/product/hager-4pole-rcb-63a-30ma-type-ac These pages show comparable specifications and can help you assess value and fit.

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.

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.

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.
