Low Voltage Circuit Breaker Testing

Circuit breakers play a critical role in protecting electrical systems from overloads and short circuits by automatically interrupting power when unsafe conditions occur. Because breaker failures can lead to equipment damage, downtime, and safety risks, proper testing and inspection are essential. PDU Cables offers tested and verified molded case circuit breakers, including visual inspections and over-current trip testing, to help ensure reliable operation in critical power distribution applications.

• Visual Inspection of Molded Case: PDU Cables performs a visual inspection of each circuit breakers molded case, to make sure the case is intact and has no visual defects from the factory. 
• Inverse-Time Overcurrent Trip Testing: Each circuit breaker is tested to verify performance to the manufacturer's trip specifications and ensure reliable operation.
• Exercising: Regular breaker cycling helps keep contacts clean, lubrication distributed, and internal mechanisms operating smoothly for reliable performance.
