Description
Pluggable pcb terminal block, 252 Series, 0 °conductor entry to boardOur pluggable pcb terminal block (item number 252-104) simplifies electrical installations. Conductors can only be connected to pluggable pcb terminal block if their strip length is between 6 mm and 7 mm. Featuring one conductor terminal along with PUSH WIRE®, this connector outperforms the competition. Our tried-and-tested PUSH WIRE® connection offers the fastest method for clamping conductors. It utilizes the conductor’s stiffness to overcome the clamping spring’s contact force. Dimensions: 14 x 11 x 10.5 mm (width x height x depth). Depending on the conductor type, pluggable pcb terminal block is ideal for conductor cross sections ranging from 0.14 mm² to 0.5 mm². It has one level. Four potentials can connect four poles using the eight clamping points The clamping spring is made of a Copper alloy, the contacts are made of electrolytic copper (ECu), and the gray housing is made of polyamide (PA66) for insulation. The contact surface is coated with tin.
