Upgrade your home or commercial electrical distribution panel with the Legrand DX³ Residual Current Circuit Breaker with Overcurrent Protection (RCBO). Designed for comprehensive dual-layer safety, this device combines the short-circuit and overload protection of a standard MCB with the earth-leakage/shock protection of an RCCB. Operating with a high-sensitivity 30mA trip threshold, it is engineered to instantly detect micro-leakages and prevent hazardous electrical shocks, making it the perfect choice for modern, high-safety electrical installations.

Key Highlights

Comprehensive Dual Protection: Simultaneously protects your circuits against overloads, short circuits, and earth leakage faults
Life-Saving 30mA Sensitivity: Instantly trips during micro earth-leakages to safeguard humans and pets from fatal electric shocks
Front-Face Leakage Indicator: Features a dedicated visual fault window on the front panel to easily distinguish between an earth-leakage trip and an overload trip
Ergonomic Design & Quality Markers: Comes with a color-coded On/Off visual indication on the dolly, an integrated label holder, and standard sliding shutters for safe wiring
Heavy-Duty Terminal Capacity: Equipped with robust 35 sq mm terminals that effortlessly support flexible wiring configurations
Certified Safety Standards: Fully ISI marked under compliance standard IS 12640-2 for guaranteed quality, durability, and reliable performance

Recommendation & Amperage Selection Guide

Choosing the correct variant ensures optimal safety and eliminates nuisance tripping. Here is where each variant is best suited:

16A Variant (Cat No. 4113 24): Best for mid-load power outlets, kitchen countertops, and dedicated appliances. Applications include microwave ovens, washing machines, small geysers (water heaters), dishwashers, and standard bedroom/living room power loops
25A Variant (Cat No. 4113 25): Best for medium-to-heavy residential loads requiring a higher continuous current ceiling. Applications include 1.5 Ton Air Conditioners (ACs), large storage water heaters, master kitchen loops, and heavy pumps
32A Variant (Cat No. 4113 26): Best for high-capacity dedicated appliances or sub-divisional panel boards. Applications include 2 Ton (or larger) Air Conditioners, specialized industrial/commercial kitchen equipment, or serving as a dedicated protector for localized distribution boards

1) What is the benefit of using an RCBO over a standard MCB?

A standard MCB only protects your wiring against overloads and short circuits (preventing fires). An RCBO does all of that plus monitors current balance to detect earth leakages. If current leaks (such as passing through a human body due to faulty insulation), the RCBO detects it instantly and cuts off power, preventing electrocution.

2) What does "30mA Sensitivity" mean, and why is it important?

Medical studies show that currents above 30mA can cause severe respiratory and cardiac damage to humans. A 30mA sensitivity rating means the device will trip within milliseconds if it detects a leakage current as tiny as 0.03 Amps, providing maximum personal safety for residential environments.

3) How do I know if the breaker tripped due to an overload or an earth leakage?

The Legrand DX³ RCBO features a dedicated front-face fault indication window. When an earth-leakage fault occurs, this distinct mechanical indicator changes on the face of the unit, allowing you or your electrician to immediately identify and troubleshoot the exact nature of the problem.

4) Can I use aluminum cables with these RCBO units?

While these RCBOs feature premium 35 sq mm terminals designed primarily for copper applications, Legrand guidelines note that for terminating aluminum cables in devices rated 32 A and above (such as the 32A variant), the use of an Entry Terminal (Cat.No 6034 48) is mandatory to ensure a safe, corrosion-free contact.

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

Choose 16A for mid-load outlets and standard appliances like microwaves and washing machines. Choose 25A for heavier loads like 1.5 Ton ACs and storage water heaters. Choose 32A for high-capacity dedicated appliances like 2 Ton+ ACs or as a sub-panel protector.
