6 Dry Contact Inputs
CIBRE-L6 6-Contact Circuit Breaker Timers are designed using advanced engineering technology to test contact timings of circuit-breakers.
CIBRE-L6 have fast, easy and accurate measurement features by our user-friendly software.
CIBRE-L6 are battery-powered devices (optional feature), which allow operators to perform tests even without power supply during field tests.
Why do we need to test circuit breakers?
It is essential 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 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 are then compared with the manufacturers’ specification to determine the performance of the circuit breaker.
CIBRE-L6 feature a 7-inch large colour touch display, which is visible under bright sunlight and dim light conditions. With the Data Management Platform (DMP Software), users can analyse and manage measurement results on PCs.
Operators can easily print the measurement results with the 2.28-inch built-in printer of CIBRE-L6. The results can also save to a USB flash drive or the device’s internal memory.
Multi-language capability and user-friendly operation menu make it easy to control CIBRE-L6.
CIBRE-L6 devices are lightweight, compact and rugged with the protection of IP67 (case closed), making them perfect for the field test.
