REFI offers a unique competitive edge by combining RCCB, surge protection, and over-voltage cut-off into a single, compact, and resettable device, eliminating the need for multiple separate components. This integrated design reduces cost, installation complexity, and maintenance compared with conventional systems. Unlike many SPDs that fail silently, REFI’s resettable mechanism restores protection without requiring part replacement. It also operates effectively even with poor grounding, giving it a reliability advantage in older buildings and underserved communities. With patent protection across several countries, REFI stands out as a safer, more affordable, and more accessible electrical protection solution.

Current electrical protection systems require multiple separate devices, such as RCCBs, SPDs, and over-voltage protectors, which increases installation cost, complexity, and maintenance needs. Many surge protectors fail silently after a lightning strike or power surge, leaving users unknowingly unprotected. In addition, the effectiveness of existing SPDs depends heavily on proper grounding, which is often poor in older buildings and low-income households, resulting in inadequate safety. These gaps expose homes, businesses, and industries to risks of electric shock, appliance damage, fire hazards, and costly replacements.

The project delivers an integrated electrical safety device, REFI (Resettable Electrical Fault Isolator)-that combines RCCB, surge protection, and over-voltage cut-off into a single unit. This all-in-one, resettable solution removes the need for multiple components, reduces installation complexity, and eliminates costly replacements after faults. Designed to operate effectively even in areas with poor grounding, REFI provides reliable and affordable protection that can be easily retrofitted into existing electrical systems without additional wiring or redesign.

The REFI device introduces a patented, resettable technology that integrates RCCB, surge protection, and over-voltage cut-off into a single compact unit, something not offered by conventional systems. Its plug-in modular design allows protection to be restored without replacing components, solving the common issue of silent SPD failure. Unlike typical surge protectors that rely on good grounding, REFI is engineered to function effectively even with poor earth impedance, making it safer and more reliable for a wider range of buildings. This retrofit-friendly innovation significantly reduces installation complexity while delivering comprehensive electrical protection in one device.
