Cummins OTEC Series

The OTEC automatic transfer switch series provides the basic features needed for primary source and generator set monitoring, generator set starting, and load transfer functions for emergency standby power applications.

The OTEC transfer switches monitor both power sources, signal generator set to start, automatically transfer power, and return the load to the primary power source once a stable utility is available. The fully integrated controller is designed for practical functionality, with LED indicators and digital pushbuttons for ease of operator use.

Cummins Power Generation switches are built to withstand thousands of switching cycles, ensuring maximum reliable operation.
