Hager 63A 4Pole 100Ma RCCB Earth Leakage Circuit Breaker (ELCB)

4P means the device has four connection poles, suitable for 3-phase systems with a neutral. It provides protection for multiple live conductors and common-neutral configurations in larger installations.

The 100mA residual current rating specifies the leakage current at which the RCCB will trip to disconnect the circuit, helping prevent electric shocks and electrical fires due to earth leakage.

A 63A breaking capacity indicates the maximum fault current the device can interrupt safely. It is suitable for circuits where the fault current is unlikely to exceed this value, providing reliable protection within that limit.

It is designed for use in systems up to 690V AC and is suitable for domestic, light commercial, and industrial installations that require leakage protection on a 4-pole configuration.

The RCCB includes an 'on' indicator and a trip indicator to show fault status, plus a manual test button to verify event functionality and ensure the device is operating correctly.

It conforms to IEC 61008-1, BS EN 61008-1, and IEC 61009-1 standards, and is CE marked, confirming alignment with international safety and performance requirements.

It's suitable for domestic, light commercial, and some industrial installations where earth leakage protection is required for multi-pole circuits, especially in 3-phase/neutral arrangements.

Power must be switched off before installation. Mount the unit on a suitable DIN rail, connect incoming supply to the line terminals (L1–L4 as applicable) and connect protected conductors to the load side. Tighten terminals to the recommended torque, then restore power and test using the front-edge test button or an equivalent protective test method.

Use the built-in manual test button to trigger a simulated leakage fault and confirm the circuit disconnects. Regular monthly testing is recommended to verify reliable operation.

If you need 4-pole, 100mA leakage protection for a larger installation, this Hager model provides compatible 4P configuration and IEC-compliant protection. For a lower-sensitivity option (e.g., 30mA) or a different pole count (2P), you can explore other RCCBs on Fepy to match your protection level and wiring needs. Compare options like 4P 30mA or 2P 100mA variants to choose the best fit for your circuit requirements.

Its rugged construction, compliance with international standards (IEC 61008-1 and IEC 61009-1, CE marked), and suitability across domestic to light commercial installations contribute to a long service life and reliable earth-leakage protection in diverse environments.

Yes, Fepy offers other RCCBs with different current ratings, pole configurations, and sensitivities to match specific installation needs. For example, you can explore 4P 100mA and 4P 30mA options or 2P variants to compare features and pricing against this model.
