Circuit Breakers

What are Circuit Breakers?

IMG_20190922_112648A Circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.

Preventative Electrical Services, services and retrofits low voltage and high voltage circuit breaker, from hundreds of amps to thousands of amps in size.

Why Test Switchgear?

Overheating, misalignment, arcing, physical damage, broken/weak springs or corona (characterized by hissing, cracking, buzzing noise and purple light emissions) are some of the problems that can affect Circuit Breaker effectiveness and efficiency.

Regular maintenance will boost your Circuit-Breakersā€™ effectiveness, safety and life span, while avoiding costly repairs.

Manufacturers have outlined procedures and recommendations for the regular maintenance of their switchgear. To ensure you get the longest possible life-span out of your breaker, components must be replaced at specific intervals and the equipment maintained.
