Description
Pluggable pcb terminal block, 252 Series, 0 °conductor entry to boardOur pluggable pcb terminal block (item number 252-307) is designed for seamless electrical installations. Strip lengths must be between 6 and 7 mm when connecting conductors to pluggable pcb terminal block. This product features one conductor terminal and utilizes PUSH WIRE®. Our PUSH WIRE® connection uses the stiffness of the conductor to overcome the clamping spring’s contact force, allowing faster and easier conductor clamping. The item’s dimensions are (24.5 x 11 x 11.8) mm (width x height x depth). Pluggable pcb terminal block is suitable for conductor cross sections ranging from 0.14 mm² to 0.5 mm².The contact surface is coated with tin.
