Hager CDC264J RCCB 63A 2-Pole 30mA Type AC (ELCB)
The Hager CDC264J RCCB (ELCB) delivers rapid disconnection at earth leakage currents, enhancing protection for people and equipment. Rated 63 A with a 30 mA sensitivity, it provides personnel-protection level earth-leakage protection for single-phase circuits. Manufactured in France and engineered to IEC standards, it offers reliable, fast fault isolation in UAE electrical installations, with a compact, durable design that fits neatly into distribution boards.

FAQ
-
What's the difference between an MCB and an RCCB/RCD?
An MCB (miniature circuit breaker) protects against overload and short-circuit currents. An RCCB (residual current circuit breaker), also called an ELCB, monitors the balance of current between line and neutral conductors and disconnects the circuit when it detects earth leakage — protecting against electric shock and fire from insulation faults. The two devices protect against different fault types and are typically installed together on a distribution board.
-
What does the 30 mA sensitivity rating mean?
30 mA is the internationally recognised threshold for personnel protection — sensitive enough to disconnect the circuit before a leakage current through a person's body becomes dangerous. It's the standard sensitivity for socket outlets and other circuits directly accessible to people.
-
What does 2-pole mean and do I need it for this circuit?
A 2-pole (1P+N) RCCB switches the line and neutral conductors together. It's used on single-phase circuits, so both conductors are isolated together the moment a leakage fault is detected.
-
Can I install this myself?
No. This is a distribution board component that must be installed and connected by a licensed electrician in accordance with local wiring regulations. Incorrect installation of an RCCB can leave circuits without leakage protection.
-
Will this fit a standard Hager distribution board?
Yes. The CDC264J is part of Hager's modular DIN-rail range and installs alongside Hager MCBs, isolators, and other DB accessories in a standard Hager consumer unit or distribution board.
