Hager 40A 2Pole 100MA Earth Leakage Circuit Breaker

Key specs: Rated current up to 40A; residual current sensitivity of 100mA; 2-pole protection (disconnection of live and neutral); halogen-free material; combines earth leakage protection (RCCB/ELCB) for enhanced safety; compact design with clearly marked terminals for easy wiring; designed to meet standard electrical safety requirements.

This model provides dual protection by combining RCCB and ELCB functionality in one device. It detects leakage currents and disconnects both conductors (live and neutral) to stop shock hazards and reduce leakage-related fires, with a compact, easy-to-wire form factor.

Ideal for both residential and commercial installations where leakage protection is important—bathrooms, kitchens, wet areas, and any circuits where extra protection against earth leakage is desired.

Before wiring, switch off the main supply. Connect Live and Neutral wires to the marked line/load terminals as indicated on the device. Ensure wires are securely tightened and the device is properly mounted in a suitable enclosure. Double-check correct polarity and that the terminal markings are clear before restoring power.

Halogen-free construction minimizes toxic smoke and corrosive gases in the event of a fault, improving safety for occupants and first responders while maintaining performance in electrical protection.

A 100mA sensitivity provides reliable protection against earth leakage that could pose shock or fire hazards in typical domestic and light commercial circuits. It balances prompt protection with nuisance tripping avoidance on normal loads.

Both offer 40A, 2-pole protection with 100mA sensitivity. Differences typically lie in housing design, mounting options, terminal layouts, and panel compatibility. You can review Schneider Electric’s equivalent product here: https://fepy.com/product/schneider-electric-40a-2pole-100ma-rccb

Siemens and Hager products provide similar protection specs (40A, 100mA, 2-pole). Differences usually appear in installation footprint and terminal arrangement. Compare with Siemens’ equivalent here: https://fepy.com/product/siemens-40a-2pole-100ma-rccb

Eaton and Hager options offer the same basic protection profile. Selection may depend on panel compatibility and physical dimensions. See Eaton’s alternative here: https://fepy.com/product/eaton-40a-2pole-100ma-rccb

Yes. Its 40A rating and 100mA leakage protection make it versatile for a range of circuits in homes and small-to-medium commercial setups, especially where enhanced earth leakage protection is desired.

visually confirm wiring is correct and terminals are secure; ensure the device is seated properly in its enclosure; if feasible, perform a professional leakage-protection test with appropriate equipment or by a licensed electrician to confirm tripping behavior under fault conditions. Regular inspection for signs of wear or overheating is advised.
