Connection Chamber Company Switch Brochure

This type of Company Switch has become the de facto standard in the entertainment industry. Developed by Union Connector in the mid-90′s, it was first produced as the PBS Series, which has since been replaced by the CSC Series. The CSC Series still contains the same basic elements – Main breaker, connection chamber, bus bar output, outlets, indicator lights and integral strain relief bar, all in a compact enclosure. The access door to the connection chamber is protected by a micro-switch that activates a shunt trip in the main breaker whenever the door is opened. When the connection chamber door is opened, the main breaker is tripped, and the exposed busbars are “cold”, allowing direct tie-in to the bus. Closing the door and resetting the breaker restores power to the bus, outlets and the connected cables. This provides a safe and reliable means to tie-in with either bare ends or cable connectors.
