What is the Wago 235-553?

PCB terminal block, 235 Series, PUSH WIRE®

Our PCB terminal block (item number 235-553) makes connecting wires quick and easy. It is perfect for custom installations with different mounting types. Conductors can only be connected to this PCB terminal block if their strip length is between 9 and 10 mm . Featuring one conductor terminal along with PUSH WIRE®, this product is highly versatile. 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. The item's dimensions are (24 x 12.8 x 12.5) mm (width x height x depth). Depending on the conductor type, this PCB terminal block is ideal for conductor cross sections ranging from 0.25 mm² to 0.75 mm².

The contact surface is coated with tin. This PCB terminal block is operated with an operating tool. THT is used to assemble the PCB terminal block. The conductor is designed to be inserted at an angle of 0°..
