Hager CEC441J RCCB 40A 4-Pole 100mA Type AC – ELCB, Made in France
The Hager CEC441J is a 4-pole residual current circuit breaker (RCCB/ELCB) rated 40A with 100mA Type AC sensitivity, built for earth-leakage protection on UAE distribution boards in residential, commercial and light-industrial installations. Manufactured in France to IEC 61008-1, it combines fast leakage tripping with long-term mechanical reliability in standard DIN-rail enclosures.

FAQ
-
What's the difference between an MCB and an RCCB/ELCB?
An MCB (Miniature Circuit Breaker) protects against overload and short-circuit faults. An RCCB/ELCB like the CEC441J monitors earth leakage current and trips on imbalance, protecting against electric shock and earth faults that an MCB cannot detect. They serve different protection functions and are often installed together in a distribution board.
-
What does the 100mA sensitivity rating mean?
The CEC441J trips when it detects a 100mA (0.1A) imbalance between live and neutral conductors. 100mA sensitivity is set for equipment and fire protection on distribution/sub-main circuits, rather than the 30mA rating used for direct personnel shock protection on final circuits — it is typically paired with 30mA RCCBs/RCBOs further downstream for full protection.
-
How many poles do I need — what does 4-pole (4P) mean for this circuit?
4-pole means the device switches all four conductors of a three-phase-plus-neutral supply (3P+N). Use a 4-pole RCCB on three-phase distribution boards or where the neutral must also be isolated; single-phase circuits typically use a 2-pole (2P) device instead.
-
Can I install this myself?
No. The CEC441J is a distribution board component and must be installed and commissioned by a licensed electrician in accordance with UAE wiring regulations.
-
What is the short-circuit/breaking capacity of the CEC441J?
It has a rated conditional short-circuit current (Inc) of 6kA and a breaking/opening capacity of 1500A, in line with IEC/EN 61008-1 requirements — sufficient for typical residential and light-commercial distribution boards.
