PRODUCT DESCRIPTION

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.

Configurations

ZBTS - Bypass/Isolation
The Zenith ZBTS Bypass/Isolation transfer switch is used in general and mixed load applications.

ZBTSD - Delayed Transition Bypass/Isolation
The Zenith ZBTSD Bypass/Isolation transfer switch is used to transfer of large motor loads, transformers, uninterruptible power supplies (UPS) systems or load shedding to a neutral "center" position.

ZBTSCT - Closed Transition Bypass/Isolation
The Zenith ZBTSCT Bypass/Isolation transfer switch is used to transfer critical loads where a "no break" transfer is desired with this switch 100msec parallel capability.

FEATURES & BENEFITS

  • Load is not interrupted during bypass & isolation operation
  • High close-in and withstand capacity
  • Automatic transfer switch is located on a draw-out mechanism to facilitate maintenance
  • Emergency power systems can be electrically tested without disturbing the load
  • Power cables do not have to be disconnected to remove automatic transfer switch
  • Bypass to any available source with ATSremoved
  • Engine start circuit maintained during bypass operation; normal power failure causes engine start contact closure even with the ATS removed
  • Diagnostic lights and detailed instructions for simple step-by-step operation
  • Mechanical and electrical interlocks ensure proper sequence of operation
  • Bypass switch contacts are closed only during the bypass-isolation operation
  • Silverplated copper bus interconnection of the transfer and bypass switches on all sizes
