Hager MCN240 MCB 40A 2-Pole 6kA Type C — Made in France
The Hager MCN240 is a 40A, 2-pole miniature circuit breaker, Made in France, designed to protect electrical installations against overloads and short circuits. With a 6kA breaking capacity and a Type C tripping curve, it suits residential, commercial, and light industrial circuits with moderate inrush currents. The 2-pole (Line + Neutral) configuration provides full double-pole isolation and mounts easily into Hager DIN-rail distribution boards used across UAE installations.

FAQ
-
What's the difference between an MCB and an RCCB/RCD?
An MCB (like the MCN240) protects the circuit and cabling against overload and short-circuit currents. An RCCB/RCD instead protects against earth leakage and electric shock. The two devices do different jobs and are typically installed together, not as substitutes for one another.
-
What does 2-pole (2P) mean and when do I need it?
A 2-pole breaker switches both the line and neutral conductors together, giving full double-pole isolation. It's typically specified where a circuit or sub-board needs complete disconnection from supply, rather than the single-pole (line-only) switching used on standard final circuits.
-
Is the MCN240 compatible with existing Hager distribution boards?
Yes. It's a standard DIN-rail (EN 60715) mounted MCB and integrates directly into Hager's modular consumer units and distribution boards.
-
What's the difference between Type B and Type C tripping curves?
Type C trips at roughly 5-10 times rated current, giving it enough margin to handle the inrush of motors, transformers, and lighting ballasts without nuisance tripping. Type B trips at a lower 3-5x threshold and suits purely resistive loads. Type C is the common choice for mixed commercial and light industrial circuits.
-
Can I install this myself?
No. This is a distribution board component and must be installed and connected by a licensed electrician in accordance with UAE wiring regulations — it is not a DIY consumer product.
