CA721/100 is a 100-pole internal jumper assembly designed for the CTS2.5UN screw clamp terminal block series. This assembly consists of a current bar, shorting sleeves, and screws that install into the center of the terminal block to interconnect multiple terminals. The 100-pole strip can be broken down to any number of poles desired, providing flexibility for custom jumpering configurations. Shorting sleeves and screws are made of nickel-plated brass to ensure reliable and mechanically safe electrical connections. This product reduces wiring time by allowing adjacent or selective terminal blocks within an assembly to be easily interconnected while leaving terminal clamps free for additional wiring, making it ideal for complex control panel and industrial automation applications.
