Why buy this product
The Push-in connection terminal blocks are characterized by the system features of the CLIPLINE complete system and by easy and tool-free
wiring of conductors with ferrules or solid conductors
The compact design and front connection enable wiring in a confined space
In addition to the testing facility in the double function shaft, all terminal blocks provide an additional test connection
Tested for railway applications
