Introduction
GE Zenith Transfer Switches are used to provide a continuous source of power for lighting and other critical loads by
automatically transferring from the normal source of power to an emergency source of power in the event that the nor-
mal source voltage falls below preset limits.
Voltage sensing and system control is performed via a state-of-the-art microcontroller located on the cabinet door. It is
designed to give highly accurate control of the transfer switch system.
All GE Zenith transfer switches are designed for use on emergency or standby systems, and are rated for total system or
motor loads. Transfer switches are UL Listed under Standard 1008 and CSA Certified under Standard C22.2 No. 178 and
IEC Listed under Standard 947.
NOTE
: A protective device such as a molded care circuit breaker or fused
disconnect switch MUST be installed on both sources of incoming
power for circuit potection and as a disconnection device.
