This ruggedly built family of power contactor switches has been specifically designed for transfer switch duty with dependability, versatility and user friendliness of prime concern.<br>The CTS power panel components, consisting of power switching co
When the normal source fails or the voltage drops to a predetermined point (usually 80% of nominal), if required, a circuit is closed to start the engine generator set. When the emergency source reaches 90% of rated voltage and 95% of rated frequency, the
All CTS switches employ the simple “over-center” principle to achieve a mechanically locked position in either normal or emergency and a high speed drive assures contact transfer in 100 ms or less. High contact pressure and positive mechanical
