Double-level terminal blocks
By Staff -- Plant Engineering, 8/1/2006
The four-conductor connection of the UT double-level screw terminal blocks is an alternative to standard feed-through terminal blocks when it comes to potential distribution. The universal FBS plug-in bridge system allows cross connections to neighboring feed-through terminal blocks. Bridging from the upper level to the lower level can be accomplished with a special FBS component. Ground terminal blocks of the same shape are designed with a snap-on foot. The double bridge shaft allows individual chain bridging by means of plug-in bridges on both levels. Corresponding standard accessories are available for testing and labeling. Either level of the UTTB 4 can be marked with ZB6 or ZBTF marking material, and users can mark the UTTB 2.5 with ZB5 or ZBFT5.
