3 and 4 wired elements such as motors, sensors, actuators and initiators are commonly
used in industry. The multi level terminal blocks (PUK 3, PUK 2 T, PUK 3 T) are designed
and developed to meet the demanding requirements of 3 or 4 wire applications. Signal,
power and ground can be connected on a single, compact 6 mm. width terminal block.

- Make wiring more practical
- Reduce the installation costs and speed the wiring.
- Provide individual cross connections for each layer. They are used at the edge of sensor
   terminal blocks.
- Provide definitive identification of positive, negative and ground connections with the help of
   internationally accepted colors for the related layers. Because of this property, they
   minimize wiring mistakes and speed wiring.
- Are ideal for limited spaces because of their compact designs.
