Circuit Breaker Repair Process


Design a high-voltage electrical control system for your auto shredder

Visual and Qualitative inspection to look for soundness, signs of overheating or excessive arcing, alignment, pressure, wear, corrosion, and indicator operation. Includes (when present) power control fingers; main contacts; arc chutes and contacts; close, trip, and cell interlock mechanisms; auto trip indicator, and breaker frame. Additional tests include insulation resistance tests of power conductors, DC contact resistance measurements, high-potential tests, and operation of the breaker in the test position.

Cut your auto shredder power bill by reducing peak energy usage

A test sheet will be supplied showing test results and observations along with recommended remedial actions. Each item is assigned a grade of A, B, or C to indicate the breaker’s condition, wear, use, and operation. Breakers given an “A” are in good condition with slight wear and used under light conditions. A “B” grade is satisfactory condition with normal wear under heavy conditions; a “C” indicates immediate action required for proper operation.

Repair and Clean up

Analysis needed to receive approval from the power company for your shredder

Once the breaker has been repaired, it will be cleaned and prepared to be put back into operation. Dust and light residue will be cleaned off. Any mechanisms that need lubrication will be attended to. If the breaker shows any abnormal corrosion or is otherwise in an abnormal condition or state, this will be reported to the customer.

About Power Studies


repairing circuit breakers

For ABB circuit breaker repair, or for any circuit breaker that has failed to operate correctly or meet the manufacturer’s performance specifications during periodic routine testing, count on the Quad Plus experts for fast circuit breaker repair. In most cases, we can complete repairs within 2 to 3 days, depending on your needs and the availability of parts and emergency turnaround service is available.

Every repair begins with a visual inspection of each circuit breaker for worn or missing mechanisms. Electrical testing and analysis are then performed to determine if there are any issues with the circuit breaker. Upon approval for repair, defective parts are removed and replaced with new parts. A final test and inspection is performed to ensure proper operation before the circuit breaker is returned.


refurbishing and reconditioning circuit breakers

Quad Plus follows strict reconditioning and refurbishment processes as defined by ANSI/IEEE C37.59 and we use only OEM or manufacturer-recommended parts without altering the breaker’s original design. We offer partial reconditioning that focuses only on problem areas or a complete teardown and rebuild of the breaker to return mature breakers into a “like new” condition. Every repair comes with a one-year warranty so you can be confident of your repaired parts.

The process begins with disassembly, inspection, cleaning, and repainting (or zinc-chromate plating) if required. The breaker is then reassembled with replacement parts and lubricated as needed. The final step is mechanical operation and electrical testing to verify proper functioning of the breaker before returning it to the customer.


retrofitted circuit breaker

Do you have breakers that are decades old and want the advanced protection features available on modern breakers, but without the expense of a new system? Quad Plus will retrofit circuit breakers to provide a robust and reliable system that reduces losses resulting from downtime and upgrades. Retrofit components can be installed using existing facilities and require no additional space, saving up to four times the area of replacing existing equipment with new systems.

Quad Plus experts will retrofit with solid-state upgrades, state-of-the-art trip units, and arc flash compliant devices. Gain additional safety and security without the hassle and expense of a complete system upgrade.

Preventative Maintenance
