Configurations
- ZB3ST - Standard (Open) Transition
The Zenith ZB3ST Bypass/Isolation transfer switch is used in general and mixed load applications. - ZB3DT - Delayed Transition
The Zenith ZB3DT Bypass/Isolation transfer switch has an adjustable time delay in the centered "off" position. This delay allows motor loads to coast down and transformer field to decay; ensuring inductive loads are re-energized after transfer with only normal inrush starting currents. - ZB3CT - Closed Transition
The Zenith ZB3CT Bypass/Isolation transfer switch is used in critical/life safety applications where a "no break" transfer is desired during periodic testing and maintenance.
