WAGO Corporation's TOPJOB®S current transformer disconnect terminal blocks simplify current transformer testing, as well as increase safety, within power monitoring applications. Designated the 2007 Series, these CT disconnect terminal blocks feature an intuitive orange three-position (Operating, Shorting and Measuring) disconnect lever. Engaging the lever fully automatically short-circuits the transformer when using the required adjacent push-in jumper.
At just 99 mm long and 8 mm wide, the 2007 Series CT Disconnect Terminal Blocks reduce panel space by up to 55% and associated costs by up to 25% when compared to traditional test switch products. Its touch proof design does not require a separate cover to be installed which eases access to test plugs and meter connections. Four marking locations help ensure wiring accuracy: on the disconnect link, on top of the terminal block and on the sides. Marking is provided via WMB marker tags or a continuous marking strip.
Available in through or ground connection versions, the 2007 Series employ CAGE CLAMP®S Spring Pressure Technology for conductor sizes 20-8 AWG. This eliminates lugs, crimps and torqueing to make all connections maintenance-free. A full complement of accessories is available; including test plugs, a lock-out plug and an optional mechanical link to gang disconnect levers together.
