Automatic Transfer Switches
ZBTE - Bypass/Isolation

ZBTE - Bypass/Isolation

The ZBTE Series Bypass/Isolation automatic transfer switch (ATS) is ideal for use in todays 7x24 service centers, data warehouses and critical healthcare facilities. These mission critical sites demand more than just continuity of power, and the ZBTE meets these challenges.

 

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 Bypass ATS capability. The ZBTE Series is ideal for use in this environment.

 

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.

 

Configurations

 

• ZBTE - 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.
