At APM Hexseal, we produce lever-actuated circuit breaker boots for mission-critical applications. Made of transparent silicone RUBRGLAS®, our circuit breaker boots extend the lifespan of breakers while allowing easy device operation and status recognition. Our distinct Back-of-Panel and Front-of-Panel styles both offer exceptional environmental protection with a continuous sealing rib around the underside of the flange.

What Are Circuit Breaker Boots?

Circuit breaker boots seal breaker switches from external elements that can lead to short circuits and fire hazards. They safeguard against a variety of indoor and outdoor conditions and contaminants, such as:

  • Extreme temperatures. Without the protection of high-quality circuit breaker boots, high temperatures can cause equipment to overheat and harm its fragile components, while freezing temperatures may otherwise allow ice to form in the actuator wells.
  • Oils, chemicals, lubricants, solvents, and more. Elevators, industrial machinery, HVAC systems, and more use a variety of lubricants, oils, and other chemical substances that can damage internal circuitry. 
  • Dust, rain, snow, salt, and more. Both indoor and outdoor applications are subject to temperature fluctuations and dust, while outdoor systems face even greater challenges with rain, snow, sun, and other weather conditions.

Whether they are secured behind or outside the breaker mounting panel, the boots create a reliable seal that allows electrical components to function in the most challenging indoor and outdoor environments.

Applications

For equipment that requires regular washdown, salt-rich environments like the coast, or even use with deicing chemicals on a highway and more, APM Hexseal’s circuit breaker boots are trustworthy in a wide range of applications and industries, including:

  • Agriculture. Circuit breaker boots ensure that farm equipment continues to operate in wet, muddy, hot, cold, or otherwise adverse environments.
  • Chemical and petroleum. The boots protect against chemical contaminants and maintain equipment operation in challenging conditions.
  • Automotive. To protect automobile components from hard wear, boots resist vibration and corrosion.
  • Marine. Circuit breaker boots guard navigation, calibration, and other equipment against saltwater, corrosion, and pressure variations should equipment be submerged in water.
  • Energy generation. This equipment optimizes electrical and mechanical system operations.
  • Electronics. These UL-recognized solutions preserve sensitive electrical systems as well as user safety.
  • Food and beverage. They protect against contamination, leaks, and aroma transfer in food and beverage processing.
  • Lighting. These boots shield lights and their internal components against weather, water leaks, dust, chemicals, and pressure changes.
  • Drilling/down hole/pump. In the drilling industry, circuit breaker boots guard against dirt and other contaminants.
  • Construction and industry. Boots safeguard equipment in these sectors from vibration, dust, oil, chemicals, corrosion, and more.
  • Military and aerospace. They protect mission-critical systems on Earth and in outer space.
  • Medical and pharmaceutical. Circuit breaker boots help fragile equipment continue to meet high standards from the FDA and other organizations.

Capabilities

Our circuit breaker boots are one of our most popular sealing solutions because they are reliable in such challenging environments. Even equipment in seemingly “safe” conditions faces a variety of dangers, including dust, temperature or pressure changes, or liquid spills. The boots have to withstand the expected (like vibration in an automotive application) and the unexpected (a spilled glass of water in an office setting).

Our lever-actuated Back-of-Panel and Front-of-Panel boots offer temperature protection ranging from -103° F to +400° F. They guard against UV light, weather, ozone, altitude pressure, leaks and splashes, salt spray, dust, fungus, and most acids and lubricating oils, giving them a lifespan of more than 25 years. Our transparent silicone RUBRGLAS® resists yellowing so the boots maintain their clarity over time, while the vibration-resistant mountings secure with self-sealing Seelskrews®.
