Product Overview

What This Model Does

The safe H series arc fault circuit breaker (AFDD) provides comprehensive protection against arc faults, overload, short circuit, residual current, over-voltage, under-voltage, and self-running temperature rise. Built to integrate with standard miniature circuit breakers and residual current devices, it delivers a compact 36mm width design suitable for space-limited residential installations. It includes LED fault indication for quick self-diagnosis and troubleshooting. Communication functions are not supported at this time.

Key Benefits

  • Combines arc fault, overload, short circuit, leakage, over-voltage, under-voltage and thermal protection in one device
  • 36mm width saves space in compact distribution boards and residential panels
  • LED fault indication enables immediate identification of fault type without external tools
  • Self-running temperature protection prevents overheating during prolonged overloads
  • Mechanical protection remains active during power loss or network failure
  • Designed for residential and space-constrained applications where safety and compactness are critical

Who It Is For

  • Electrical wholesalers adding arc fault protection to their low-voltage product range
  • Panel builders integrating multi-protection devices into compact distribution boards
  • Residential electrical contractors installing safe, space-saving breakers in tight enclosures
  • Solar and EV charger installers needing enhanced protection in confined spaces
  • OEM buyers requiring a compact, multi-functional breaker for branded distribution solutions

Problems It Solves

  • A single point of failure in a circuit due to undetected arc faults leading to fire risk
  • Lack of space in existing panels preventing the addition of separate protection devices
  • Difficulty identifying fault types without external testing equipment or diagnostics
  • Overheating from sustained overloads without automatic thermal shutdown
  • Need to install multiple devices (MCB, RCCB, AFCI) when one integrated unit suffices

Application Scenarios

  • Residential electrical panels where space is limited and fire risk must be reduced
  • Apartment buildings and rental units with shared or confined distribution boards
  • Renovations of older homes with outdated wiring that may develop arc faults
  • Small distribution boards in smart homes where multiple protection types are needed
  • Installations where quick fault diagnosis is needed without a multimeter or tester

Comparison

How It Compares

Conventional MCB with separate AFCIOne integrated device instead of two, though AFCI function is limited to arc detection only
Standard RCBO with no arc fault detectionAdds arc fault protection, but may not detect low-energy arcs as reliably
Smart AFDD with IoTLower cost and simpler installation, but lacks remote monitoring and control

Use Guide

  1. Connect live and neutral conductors to the input and output terminals as per polarity
  2. Ensure the breaker is switched off before making connections
  3. Turn on the main supply and confirm the device holds under normal load
  4. Check the LED indicator after a trip to identify the fault type
  5. Reset the breaker manually after resolving the fault condition
  6. Keep the LED indicator visible for routine self-checks and troubleshooting
FAQ

Questions About the safe H series arc fault circuit breaker AFCI/AFD
