The CB MC2 main contact module increases convenience and safety during tests with CIBANO 500. It also makes the dynamic contact resistance test possible, which detects wear-related problems with main and arcing contacts. All tests can be carried out without rewiring.
The circuit breaker can be grounded on both sides to prevent dangerous voltages on the equipment. A direct attachment of the CB MC2 modules to the interrupter units keeps the high-current cables short and minimizes the set-up time. The digital connection to CIBANO 500 considerably reduces interference.
Dynamic contact resistance test
High-current cables are kept as short as possible (weight reduction)
Low interference due to the digital connection to CIBANO 500
Fast test set up and reduced risk of wiring errors
