When an arc flash occurs, temperatures can soar to levels comparable to the surface of the sun. In such moments, every second and every layer of protection matters. Arc Stopper® garments are engineered with advanced flame-resistant (FR) and arc-rated (AR) materials to create a powerful barrier between workers and these extreme hazards.

Built for Real Protection

Each garment is designed to self-extinguish, resist melting, and absorb incident energy, helping to minimize severe burns and injuries. Behind every Arc Stopper® layer is science — and a commitment to keeping workers safe in the most demanding electrical environments.

How It Works

1. Shield Against Extreme Heat

Arc Stopper® fabrics form a thermal barrier that blocks the intense heat and radiant energy released during an arc flash, providing critical protection within milliseconds.

2. Inherent Ignition Resistance

Our materials are permanently flame resistant — they will not ignite, melt, or continue to burn after the heat source is removed. The protection is built into the fiber itself, not just applied on the surface.

3. Defense Against Molten Metal
An arc flash can eject molten metal and hot debris at high speed. Arc Stopper® garments are designed to withstand both the initial flash and secondary impacts, keeping the wearer safe from multiple types of thermal hazards.

4. Layered Thermal Insulation
Through advanced fabric systems and optional multi-layer combinations, the garments provide superior insulation to reduce heat transfer and prevent second-degree burns.

Engineered for Safety. Proven in Performance.

From design to certification, every Arc Stopper® garment reflects WLTech’s commitment to professional protection — combining science, safety, and comfort for those who face the most extreme electrical risks every day.
