Industrial Circuit Breakers & Distribution Panels

What Defines an Industrial Circuit Breaker?

Industrial circuit breakers serve the same purpose as the breakers found in the home. However, they must be capable of handling much higher voltages, due to the needs of industrial machinery and infrastructure. For example, the typical residential circuit breaker is rated for either 120V or 240V, while industrial breakers must be capable of handling anywhere between 480V to 15,000V. Because they are installed in harsher environments than those found in the average home, industrial circuit breakers also must be constructed to differnet standards. Another key difference between breakers used in the home and in industrial facilities is the type of maintenance each requires. For those found in the home, a simple visual inspection is usually all that’s needed. But for industrial circuit breakers, the process is more involved. These typically require contact resistance testing,, arc flash analysis, and infrared scanning to check for hot spots.

Key Features to Look for in Industrial-Grade Circuit Breakers

Considerations when selecting an industrial circuit breaker include:

• High voltage ratings of at least 480V
• High amperage
• Adjustable trip units
• Metal-enclosed housings
• Rugged construction
• Extended duty ratings
• Monitoring and diagnostics capabilities

Comparing Distribution Panels and Circuit Breakers in Industrial Settings 

Distribution panels are responsible for ensuring power is routed to the proper systems within an industrial facility. They direct the flow of power from the transformers through circuits to the equipment to ensure each machine or system receives the proper amount of power on a consistent basis. The role of the circuit breaker is to serve as an emergency safety valve of sorts. If the power running through the circuit exceeds the proper amount, the breaker is tripped and the circuit is opened. This serves to prevent overloads that can lead to serious damage to the equipment as well as unsafe conditions that could pose a threat to nearby workers or other assets.

Applications and Environments for Industrial Circuit Breakers

Industrial circuit breakers are found throughout a wide range of industrial and commercial facilities. Essentially, anywhere electrical loads exceed the specifications of standard residential breakers, industrial circuit breakers are required. These include manufacturing plants, data centers, utility substations, oil and gas installations, and anywhere large-scale HVAC systems are installed. Current Midwest offers breakers and distribution panels ideally suited for these and other rugged environments.

How to Specify the Right Industrial Circuit Breaker for Your System

There’s more to determining the right circuit breaker for your systems than whether it fits into the panel. You need to know the maximum current load of the circuit, for example. This ensures you have the proper amperage rating to prevent damage or excessive tripping. The breaker’s voltage rating also needs to match the circuit. Another critical consideration is the maximum fault capacity, which tells you how high the fault can be while still being safely interrupted by the breaker.

In terms of the physical properties of the breaker unit, it’s necessary to choose breakers that are rated for use in your specific environment. For example, those used in areas that experience high temperatures and/or moisture levels should be capable of withstanding them. Finally, you need to think about compliance with codes such as those surrounding ground fault or arc fault circuit protection, as certain systems may require specialized breakers.

Maintenance and Lifecycle Considerations for Industrial Circuit Breakers

 Industrial breakers need more maintenance than residential breakers. In addition to visual inspections, industrial breakers need regular testing for insultation resistance, contact resistance, over-potential, and breaker timing. It’s also recommended that each one be tested to ensure it trips when it should. Finally, calibration performed by experienced technicians will ensure the breakers will function as needed under the right conditions. Refer to the manufacturer’s guidelines for recommended maintenance procedures as well as expected lifecycle spans.
