Two new feature upgrades add measurement and control functions to the CrossMT measurement technology module. The new ”energy counter” feature enables 4-quadrant measurement by recording and counting positive and negative energy values (active, reactive and apparent). This means you always have a complete overview of the energy flow and consumption in the system.
The ”motor management” feature upgrade enables the CrossMT to control a direct or reversing contactor combination via its auxiliary outputs and to use the CrossMT as a ‘motor protection switch’ including adjustable tripping characteristics via 8 different trip classes. Together with the EQUES® adapter, the classic motor starter combination is realised with a width of 45 mm and upgraded using the measurement technology of the CrossMT. The motor feeder can be fused using a classic fuse holder (e.g. AMBUS®) directly on the EQUES® adapter or via group fusing using the CRITO® or QUADRON® power supply module.
