307-PC /-PCM
Tab/Screw Terminal Block
Star-shaped tab arrangement
DESCRIPTION
A combination of straight and angular tabs and straight screw connections, these connector blocks are particularly suitable for the mains connection of electrical equipment. They are available in various sizes, pole numbers and types for individual applications. Depending on the application requirements, they are available in different number of poles and variants. The tabs are suitable for receptacles to DIN 46247 and assembled in packets containing multiple ports (maximum of 6 ports per pole) with a metal rivet which results in low contact resistance. Due to the variable and extensive assembly combinations of the poles, a high packing density is achieved. At the end of the connectors a fixing hole is provided. Flexible conductors may only be used with core cable ends and cable lugs. At a mixed assembly, we ask for a sketch according to order illustration (please see next page), especially for the orientation of asymmetric packets. Due to the variety of designs, a total list of part numbers is not possible. Note concerning the variants: ..-PC: single level ..-PCM: multi level
