Protective conductor double-level terminal block, connection method: Push-in connection, cross section: 0.14
mm² - 4 mm², AWG: 26 - 12, width: 5.2 mm, color: gray, mounting type: NS 35/7,5, NS 35/15
Your advantages
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
