Bypass / isolation automatic transfer switch
120 - 600 V, 100 - 4 000 A | ZBTS series GE Automatic Transfer Switches

The Zenith ZBTS Series of Bypass/Isolation automatic transfer switches (ATS) are built for business and industrial critical applications requiring the reliability and enhanced operation. The ZBTS Series uses the MX250 microprocessor control system, which includes features specified for use in business and industrial critical applications. It also provides an intuitive user interface, communications capability and self diagnostics.
In business and industrial critical applications power cannot be interrupted to perform maintenance of automatic transfer switches. In such circumstances, a bypass/isolation switch is essential and is often required by code.
Zenith ZBTS Series Bypass-Isolation Transfer Switches are the solution when interruption of power during service or testing is not acceptable. Consisting of two major modules-the Automatic Transfer (ATS) and the Bypass/Isolation Switch. The ZBTS Series incorporates the rugged construction of all our ZTS Series automatic switches with a quick make/quick break bypass switch manual load transfer handle and our control/interlock system, which consists of both mechanical and electrical interlocks.
The bypass uses normal failure sensing and a time delay to start the engine automatically if a failure occurs when the ATS has been removed for service-which can be done without disturbing the load.
