The CBL bypass-isolation transfer switches combine a draw-out automatic transfer switch with isolation mechanism and a manual bypass transfer switch, to provide redundant power transfer and re-transfer capability where reliable power is paramount to the safety and vitality of our communities. These products are specifically designed to provide a convenient and robust means to satisfy the NFPA 70 Article 700 and 708 requirements for redundant transfer equipment.

Utilizing the proven Cummins BT mechanism architecture and integrating it with the new premium PC80 transfer switch control which provides standard market leading features such as integral Modbus TCP/IP and RTU communication and NFPA 70 genset start signal integrity.

The transfer switches are designed for operation and switching of electrical loads between primary and alternate power sources. They can be used in utility-generator set, utility-utility, generator set-generator set, or three- source system (dual standby) application types.

The CBL transfer switches are suitable for use in emergency, legally required and optional standby applications. The integral automatic transfer switch control monitors both power sources, signals the generator set to start and automatically transfers the load to the alternate power source. When the preferred power source returns and has stabilized, the load is automatically transferred back.
