Protect your property, equipment, and electrical installations from hidden hazards with the Legrand RX³ Residual Current Circuit Breaker (RCCB). This premium safety device specializes in identifying earth leakage faults before they lead to electrical fires or equipment breakdowns. Operating with a medium-level 100mA sensitivity, it acts as a reliable fire-protection shield for your entire electrical network, ensuring stable operation while keeping your premises secure from catastrophic leakage-induced faults.

Key Highlights

Dedicated Fire Prevention: Features a 100mA sensitivity rating designed specifically to prevent fire outbreaks caused by tracking currents or insulation deterioration
Bi-Connect Lower Terminals: Built with a specialized dual-connection bottom terminal array that effortlessly accommodates both standard wire links and fork/pin-type busbars
Ergonomic Front Handling: Equipped with an easy-to-operate mechanical toggle and an integrated manual test button on the front face to check the health of the internal circuit monthly
Robust Core Build: Manufactured from high-grade, heat-resistant thermoplastic that provides long-term operational durability and flame retardancy
Seamless Panel Integration: Standard modular structural layout allows quick clip-mounting onto any standard DIN rail without specialized tools
Certified Compliance: Fully designed and tested in strict accordance with national and international quality frameworks (IS 12640)

Recommendation & Amperage Selection Guide

The 100mA sensitivity classification makes this device highly effective as a main or sub-main protection layer. Choose the appropriate current variant depending on your total concurrent load:

25A Variant (Article Code: 4024 92): Best for standard residential apartments, independent floors, or sub-distribution zones managing everyday low-to-medium consumption loads. Applications include small residential setups, dedicated kitchen sub-boards, small offices, or studio apartments with standard electrical distribution
40A Variant (Article Code: 4024 93): Best for medium-to-large multi-room homes, retail shops, or high-density appliance zones that operate multiple systems simultaneously. Applications include modern multi-bedroom houses with multiple air conditioners, professional office spaces, workshops, or utility sub-panels running continuous commercial equipment

1) What is the main difference between a 30mA RCCB and a 100mA RCCB?

A 30mA RCCB is a high-sensitivity device meant for direct human protection to prevent fatal shocks. A 100mA RCCB is a medium-sensitivity device primarily focused on protection against electrical tracking fires. It acts as an overall line supervisor where a 30mA device might cause nuisance tripping due to normal network background leakage.

2) Does this RX³ RCCB protect my appliances against overloads or short circuits?

No, a standalone RCCB only detects earth leakages and ground faults. To safeguard your wiring and appliances against short circuits or heavy current overloads, you must couple this device with a standard upstream Miniature Circuit Breaker (MCB) or use an integrated RCBO.

3) Can I connect aluminum cables directly into these terminals?

While these terminals are built for copper connections, if you must connect aluminum cables — particularly for the higher-load 40A variant — Legrand specifies that using a dedicated 50 mm² Entry Terminal (Article Code: 6034 48) is mandatory to prevent terminal degradation.

4) What is the purpose of the 'T' button located on the front face of the RCCB?

The 'T' button is a manual testing mechanism. Pressing it creates a safe internal simulated fault to ensure the mechanical tripping linkage works flawlessly. Legrand recommends pressing this test button once a month to verify that your system safety stays active.

5) Which amperage variant should I choose for my property?

Choose the 25A variant for standard residential apartments, studio units, or small offices with everyday consumption loads. Choose the 40A variant for larger multi-bedroom homes, retail shops, or spaces running multiple air conditioners and heavy appliances simultaneously.
