Hager 63A 4Pole 30Ma Earth Leakage Circuit Breaker (ELCB)

It monitors residual current across four poles and uses a relay to trip the circuit when leakage or fault currents exceed the preset safety limits. It also features selectable voltage sensing and a built-in diagnostic function to help identify system problems.

Key aspects include: 4Pole ELCB with relay control, selectable voltage sensing, adjustable settings to fit different applications, built-in diagnostic capability, and protection against electric shocks from leakage or contact with live conductors.

It's ideal for protecting sensitive electrical appliances and circuits where leakage safety is critical, including wet or humid environments where water exposure risk exists, as well as general protection of electrical systems and occupants.

General steps: turn off power, mount the device securely (as designed for four-pole configurations), connect input/output lines per the wiring diagram, enable the selectable voltage sensing as needed, and use the built-in diagnostic feature to verify correct operation. If unsure, consult a licensed electrician.

Use the device’s built-in diagnostic feature to check for proper operation and perform a controlled test if available on the unit. Regular testing helps ensure the leakage protection is functional and ready to trip when necessary.

Ensure installation complies with local electrical codes and safety standards. Use the device only within its rated voltage and current capabilities, protect it from moisture and physical damage, and have a qualified electrician perform installation and periodic checks.

An ELCB (earth leakage circuit breaker) monitors leakage current to earth and trips to prevent shock, while a regular MCB protects against overcurrent and short circuits. An RCCB (a form of residual current device) focuses on detecting imbalance between live and neutral; this Hager unit combines four-pole protection with leakage detection for broader safety.

Yes, its design emphasizes protection against leakage and shocks, making it suitable for environments with higher moisture or potential water exposure, provided the installation itself remains compliant with enclosure ratings and safety guidelines.

Choosing Hager typically offers reliable safety performance, a built-in diagnostic feature to simplify troubleshooting, and four-pole protection with selectable sensing. It’s designed to safeguard sensitive appliances and enhance overall circuit safety, making it a strong value for critical installations.
