A busbar insertion system is an electrical connector used to connect two or more devices together. It is a safe and reliable way to connect electrical equipment and is easy to use. The system consists of busbars, which are metal bars used to conduct electricity, and circuit breakers, which are electrical devices used to interrupt the current. The busbar plug-in system is available in two different sizes, 250A and 400A. The 250A size is for three-pole and four-pole circuit breakers, and the 400A size is for four-pole circuit breakers. The busbar plug-in system is UL listed and CSA certified.
