Product Overview

What This Model Does

The Safe IoT AFDD is a compact, 36mm-wide arc fault detection device that combines conventional protection with IoT-enabled remote monitoring and control. It detects arc faults, short circuits, overloads, leakage, over-voltage, under-voltage, and self-running temperature faults in a single device. Designed for use in residential, commercial, and heritage buildings, it reduces fire risk from electrical faults and supports remote configuration via IoT. It integrates with standard MCBs and RCCBs, and is suitable for control and management in systems where electrical safety and automation are critical.

Key Benefits

  • Detects arc faults caused by insulation damage or loose connections, a leading cause of electrical fires
  • Combines arc fault, short-circuit, overload, leakage, over-voltage, under-voltage and thermal protection in one device
  • Remote control and automatic reclosing via IoT eliminate the need for on-site visits after a trip
  • Compact 36mm width saves space in distribution boards compared to separate devices
  • LED fault indication helps identify fault type quickly during troubleshooting
  • Configurable protection thresholds allow customisation of current, leakage, voltage and timing settings

Who It Is For

  • Electrical wholesalers adding an advanced protection device to their conventional MCB and RCCB range
  • Panel builders integrating a multi-functional protection device into distribution boards
  • Facility managers responsible for electrical safety across multiple buildings with remote access needs
  • Smart home and building automation brands sourcing an IoT-enabled protection device for integration
  • Solar and energy management contractors who need intelligent monitoring and fault prevention in electrical systems

Problems It Solves

  • An electrical fire starts due to undetected arc faults in aging or damaged wiring
  • A circuit trips due to a minor fault, requiring an engineer to travel to reset it manually
  • Multiple protection devices are needed for different fault types, increasing panel space and cost
  • Faults go undetected because there is no visual or remote indication of the cause
  • Protection settings are fixed and cannot be adjusted for different load types or environments

Application Scenarios

  • Residential buildings where electrical wiring ages and arc faults become more likely
  • Museums and libraries with valuable assets where fire risk from electrical faults must be minimised
  • Commercial offices with multiple circuits requiring automated monitoring and remote reset
  • Historic buildings with outdated wiring systems that need enhanced protection without full rewiring
  • Smart building systems where electrical safety is managed through a central IoT platform

Comparison

How It Compares

Conventional MCB with separate AFCIOne device instead of two, though the AFCI may lack IoT control
MCB plus RCCB plus separate AFCIReduces panel space and wiring complexity, but adds IoT functionality
Basic AFDD without IoTAdds remote monitoring and configuration, but requires a network connection

Use Guide

  1. Ensure the device is correctly wired with the correct pole count and rated current for the circuit
  2. Power on and confirm the device holds under normal load before enabling IoT functions
  3. Connect the device to the SafeH IoT platform via the provided app or web interface
  4. Set protection thresholds for current, leakage, over-voltage, under-voltage and timing as needed
  5. Use the LED indicator to identify fault types during troubleshooting and reset as required

FAQ

Questions About the Safe IoT AFDD

What is the maximum rated current for the Safe IoT AFDD

The maximum rated current is 40A, with a 40A rack rating.

Does it still protect the circuit if the network is down

Yes. All mechanical protection functions—arc fault, short circuit, overload, leakage, over-voltage, under-voltage and thermal—work independently of the network.

Which protection functions are included

Arc fault, short circuit, overload, leakage, over-voltage, under-voltage, and self-running temperature protection.

Can the protection thresholds be adjusted

Yes. The SafeH IoT platform allows configuration of current, leakage, voltage and timing thresholds.

Can we have it supplied under our own brand

Yes. We offer ODM services and can print your branding on the housing and packaging. Send your artwork and required current ratings.

What are the minimum order quantity and lead time

Both depend on the current rating and branding requirements. Email [email protected] with your model list and quantities for a current answer.
