Product Overview

What This Model Does

The safeHT AFDD/AFCI is a smart arc fault detection device integrated with a miniature circuit breaker and residual current protection function. It provides combined protection against arc faults, short circuits, overloads, electric leakage, over-voltage, and under-voltage. Built to detect dangerous electrical arcs before they cause fire, it adds remote monitoring and configurable protection thresholds via WiFi/BLE/GPRS. The device includes a LED fault indicator for self-diagnosis and fault type identification, supporting data collection and custom application integration for smarter electrical safety management.

Key Benefits

  • Detects and interrupts dangerous arc faults that standard MCBs cannot, reducing fire risk
  • Combines arc fault, overload, short-circuit, leakage, over-voltage and under-voltage protection in one device
  • Remote monitoring and adjustable protection thresholds via WiFi/BLE/GPRS allow real-time system oversight
  • LED fault indication enables quick self-check and fault type identification without external tools
  • Supports data logging and custom applications for integration into larger building or energy management systems
  • Maintains mechanical operation and protection functions even when network is down

Who It Is For

  • Electrical wholesalers expanding into smart safety devices
  • Panel builders designing distribution boards with integrated arc fault protection
  • Smart home and building automation brands sourcing a multi-protection IoT device
  • Solar EPC contractors installing systems where arc faults from PV wiring are a risk
  • Facility managers responsible for electrical safety across multiple sites

Problems It Solves

  • A circuit trips due to an undetected arc fault, leading to a fire that could have been prevented
  • Multiple protection devices (MCB, RCCB, AFDD) are needed, increasing panel space and wiring complexity
  • No visibility into fault types or protection thresholds after a trip, delaying troubleshooting
  • Lack of remote monitoring means a fault is only discovered after a site visit
  • Standard breakers do not detect arcing faults, which are a leading cause of electrical fires

Application Scenarios

  • Residential and commercial buildings where electrical fires from aging wiring or loose connections are a concern
  • Rental properties and student housing where unattended circuits need continuous protection
  • Smart home systems requiring integrated fire prevention and remote monitoring
  • Industrial sites with sensitive equipment vulnerable to over-voltage or under-voltage events
  • Panel builders integrating a single device that replaces multiple protection components
Technical Features

How It Is Built

  • Integrated arc fault detection, short-circuit, overload, leakage, over-voltage and under-voltage protection
  • Supports remote monitoring and threshold setting via WiFi/BLE/GPRS
  • Configurable protection values including limit current, leakage action value, over-voltage and under-voltage thresholds
  • LED fault indication for self-diagnosis and fault type judgment
  • Mechanical trip mechanism for overload and short-circuit protection independent of network

Materials and Construction

  • Silver-alloy contacts with a thermal-magnetic trip mechanism
  • Integrated IoT module (WiFi/BLE/GPRS) inside the breaker body
  • LED indicator mounted on the front face for fault status

Quality Control

  • Remote communication and threshold setting tested on every finished unit
  • Insulation and dielectric withstand test performed before packing

Comparison

How It Compares

Conventional MCB + separate AFDDReduces panel space and wiring complexity, though the AFDD function is now embedded
MCB + RCCB + AFDDOne device replaces three, but protection logic is now managed in firmware rather than mechanical linkage
Standard AFDD without IoTAdds remote monitoring and configurable thresholds, but requires a network connection

Use Guide

  1. Switch on manually and confirm the device holds under normal load before initial setup
  2. Pair the device via the manufacturer’s app using WiFi/BLE/GPRS for remote access
  3. Set protection thresholds (limit current, leakage, over/under voltage) in the app as needed
  4. Use the LED indicator to identify fault types during troubleshooting
  5. Keep the manual handle accessible for on-site isolation when required
FAQ

Questions About the safeHT AFDD/AFCI

What protection functions does it include

Arc fault, short circuit, overload, electric leakage, over-voltage, and under-voltage protection.

Can it work without a network connection

Yes. The mechanical protection functions (overload, short-circuit, leakage) work independently of the network. Only remote monitoring and threshold adjustment require connectivity.

Which communication methods are supported

WiFi, BLE, and GPRS for remote monitoring and configuration.

What thresholds can be adjusted via the app

Limit current, leakage action value, over-voltage threshold, and under-voltage threshold.

How does the LED indicator help with troubleshooting

It shows the fault type (e.g., arc fault, leakage, over-voltage) for quick self-diagnosis without external tools.

Can we have it branded under our own name

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