Breakers that do more November 1st 2006 "The primary role of MCCBs is circuit protection, but the latest products can do much more," says John Towersey, of Moeller Electric. Moulded-Case Circuit-Breakers (MCCBs) work by monitoring the current in the circuit they are protecting. Information about that current is useful as a guide to system performance and as an aid to faultfinding but, with ordinary MCCBs providing access to this information means investing in monitoring equipment. MCCBs with electronic trips are changing this situation, since they can be designed to capture and store data. This means that engineers investigating a breaker trip can now have easy access to diagnostic information and users can be given advance warning of impending trip conditions. This has been taken into consideration in the development of Moeller Electric's latest NZM range of MCCBs. With ratings from 40A to 1,600A and braking capacities up to 150k its breakers provide comprehensive communication and data management. More articles from Moeller Electric Ltd: |
