Hager CEC464J RCCB 63A 4-Pole 100mA Type AC — ELCB Made in France

Hager CEC464J RCCB 63A 4-Pole 100mA Type AC (ELCB)

The Hager CEC464J is a 4-pole residual current circuit breaker (RCCB/ELCB) rated 63 A with 100 mA sensitivity, designed for earth-leakage protection on higher-current residential, commercial, and industrial distribution boards. Manufactured in France, it monitors line and neutral current continuously and disconnects the circuit rapidly on detecting an earth fault, reducing the risk of electrical fire and equipment damage from insulation faults. Type AC sensing suits standard AC installations.

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 100 mA sensitivity rating mean?
  100 mA sits between 30 mA personnel-protection devices and 300 mA fire-protection devices. It is commonly used for equipment and fire protection on distribution circuits where a very low trip threshold isn't required, tripping on the larger leakage currents typical of insulation faults or equipment failure.
• What does 4-pole mean and do I need it for this circuit?
  A 4-pole RCCB switches all three phase conductors and the neutral together. It's used on 3-phase, 4-wire circuits — typically main incomers or distribution boards feeding 3-phase loads — so both phase and neutral are isolated together on a leakage trip.
• 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 CEC464J 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.
