Hager CFC464J RCCB 63A 4-Pole 300mA Type AC — ELCB

The Hager CFC464J is a 63A, 4-pole residual current circuit breaker (RCCB/ELCB) with 300mA Type AC sensitivity, made in France for earth-leakage protection on medium-to-large residential, commercial, and light industrial installations in the UAE. Its 300mA rating is calibrated for fire and equipment protection on distribution circuits rather than individual socket outlets.

Key Features

  • Rated current: 63A, 4-pole (3P+N) configuration
  • 300mA Type AC sensitivity — fire/equipment protection level
  • Rated voltage: 240–415V AC, 50Hz
  • Breaking capacity (Idm): 1.50kA; conditional short-circuit current (Inc): 6kA per EN 61008-1
  • IP20 protection rating, compact 4-module DIN rail width
  • Screw terminals (top) and biconnect terminals (bottom); 1–25mm² rigid / 1–16mm² flexible conductor capacity
  • Rated for 4,000 mechanical and 2,000 electrical operating cycles
  • Made in France by Hager, compliant with IEC/EN safety standards

FAQ

  • What's the difference between an MCB and an RCCB/RCD?
    An MCB protects a circuit from overload and short-circuit current. An RCCB/RCD like the CFC464J monitors for earth leakage current and trips to prevent fire and equipment damage — it does not provide overload protection. The two are typically installed together in a distribution board.
  • What does the 300mA sensitivity rating mean?
    300mA is a fire/equipment-protection threshold rather than a personnel-protection one: the CFC464J trips on larger leakage currents, making it suited to main incomers and distribution circuits where nuisance tripping from cumulative leakage must be avoided, while 30mA devices are used on individual final circuits for shock protection.
  • How many poles do I need?
    The CFC464J is a 4-pole (3P+N) device for three-phase supplies with neutral, protecting all three phases and the neutral conductor. Use a 2-pole RCCB for single-phase circuits instead.
  • Can I install this myself?
    No. This is a distribution-board component that must be installed and commissioned by a licensed electrician in accordance with UAE wiring regulations.
