Commercial Breakers

When it comes to the safety and efficiency of your commercial electrical system, having reliable and high-quality circuit breakers is crucial. That's why we are proud to offer our commercial bolt-on breakers, the ultimate solution for all your electrical needs.

Bolt-on Breakers for Commercial and Industrial Applications

Bolt-on breakers are a type of circuit breaker that is designed to be securely bolted onto the electrical panel bus bar. Unlike plug-in breakers that simply clip onto the bus bar, bolt-on breakers require a more secure connection to the electrical panel. Bolt-on breakers have a threaded bolt or screw that is used to attach them to the panel. This design ensures a more stable and secure connection that is less likely to loosen or disconnect over time, making them a safer and more reliable option for commercial and industrial applications. Bolt-on breakers are commonly used in larger commercial and industrial applications where more power is required, and where a higher degree of safety and reliability is necessary.
