Panduit PSL-MCB (Pre-wired SystemLink® Modular Cable System) is a modular, flexible, and cost-effective method of wiring customer specified enclosures that provides a guaranteed solution. The PSL-MCB system is a wiring solution that combines the power of spring-clamp terminations, and a pre-wired modular cable system. By using standard connection block terminations, the PSL-MCB system eliminates the need to physically terminate each conductor. This minimizes job site installation labor and cost. The modular cabling aspect of the system also enables customers to easily add, remove and rearrange control components without having to rewire components. The fully pre-wired and tested harness assemblies help to reduce installation time and cost. The PSL-MCB is a great solution for customer applications where testing and maximum flexibility are desired.
