The SCOT M3K Circuit Breaker Time Interval Meter is a reliable testing instrument designed to measure the operating time of HV and EHV circuit breakers in live switchyard conditions. This compact and portable circuit breaker timing test kit is widely used by power utilities, substation commissioning engineers and testing laboratories for verifying breaker performance.
The SCOT M3K measures and displays OPEN, CLOSE and CLOSE-OPEN timing of main contacts of three poles simultaneously, helping engineers detect mechanical defects and ensure safe operation of high-voltage breakers.
