ZBTE Bypass/Isolation Standard (Open) Transition
ZBTE Bypass/Isolation Standard (Open) Transition

In mission critical, process critical, and healthcare 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 ZBTE 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 ZBTE Series incorporates the rugged construction of all our ZTE 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.

Poor power quality damages equipment and increases maintenance costs. Inherent power problems stay hidden when testing is ineffective or incomplete. Going beyond source switching and addressing the issues of complete power quality requires a whole new level of ATS capability.

Configurations
  • ZBTE - Standard (Open) Transition Bypass/Isolation
    The Zenith ZBTE Bypass/Isolation transfer switch is used in general and mixed load applications.
  • ZBTSE - Delayed Transition Bypass/Isolation
    The Zenith ZBTED 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.
  • ZBTECT - Closed Transition Bypass/Isolation
    The Zenith ZBTECT Bypass/Isolation transfer switch is used to transfer critical loads where a "no break" transfer is desired with this switch 100msec parallel capability.
