CIBRE-L6B BLUE, 6-Contact Circuit Breaker Timer is designed using advanced engineering technology to test contact timings of circuit-breakers. CIBRE-L6B BLUE has fast, easy and accurate measurement features by its user-friendly software. CIBRE-L6B BLUE is a battery-powered device, which allows users to perform tests even without power supply during field tests.
Why do we need to test circuit breakers?
It is very important to test circuit breakers regularly. Contact Timing Tests and Motion tests are performed to determine the optimal performance of the breakers. The testing can determine improper breaker operations in case of system fault and to improve system reliability.
Contact Timing Tests
Contact timing tests are performed to compare the breakers’ main & resistor contact performance against the manufactures specifications.
The breakers OPEN, CLOSE, OPEN-CLOSE, CLOSE-OPEN & OPEN-CLOSE-OPEN operations are timed in milliseconds (ms) and cycles and then compared with the manufacturers’ specification to determine the performance of the circuit breaker.
CIBRE-L6B BLUE features with a 4.3-inch large colour touch display, which is visible under both bright sunlight as well as dim light conditions. With the HighTest Data Management Platform (DMP Software), users can analyse and manage measurement results on PCs. Operators can easily print the measurement results with the 2.25-inch built-in printer of CIBRE-L6B BLUE. The results can also save to a USB flash drive or to the device’s internal memory.
Multi-language capability and user-friendly operation menu make it easy to control CIBRE-L6B BLUE.
CIBRE-L6B BLUE is a light-weight, compact and rugged device with the protection of IP67 (case closed) which makes it perfect for the field test.
