Our customers deserve the peace of mind that their purchased circuit breakers will work as originally designed and built. Testing leads the way in providing that assurance.

"What is testing?"

Testing is the process we use to assure that every circuit breaker that leaves our facility matches or exceeds its original factory design standards. This includes (but is not limited to) interrogating trip curve parameters, contact resistance, and insulation resistance.
