The GE Zenith ZTX Automatic Transfer Switch complements remote
start generator sets allowing the standby power system to be fully automatic. A full
range or ratings are available from 40 amps to 400 amp with indoor and outdoor enclosures.
Made in USA 
Application Flexibility
The ZTX Automatic Transfer Switch combines reliability and flexibility in a small,
economical package for transferring loads between the utility and generator sets.
The XTX Transfer Switches work together with any remote-start generators using two-wire
control. The control monitors utility and emergency standby power generator set
power. When utility power fails or is unsatisfactory, the control starts the
generator set and transfers the load to the generator set. The transfer panel
immediately senses when utility power is restored. It automatically transfers back
to utility power, shutting down the generator and instantly resetting itself for the next
power interruption. No action is required by site staff.
Enclosures
The transfer panel and control are mounted in a single door NEMA 1 (indoor) or 3R
(outdoor) enclosure.
Positive Interlocking
Mechanical contactor interlocking prevents simultaneous closing of normal and
emergency contacts. Independent break-before-make action positively prevents
dangerous source-to-source connections.
Microprocessor Control
Reliable, microprocessor based control system with undervoltage monitoring of the
utility and voltage and frequency sensing of the generator, standard time delays.
This switch comes standard with GE Zenith's MX60 control panel (supersedes the
R-M4 control panel). This controller provides timing functions, voltage
& frequency sensing, exerciser and operates the external
membrane keypad/indications.

Specs
NOTES:
1) The start time delay prevents nuisance generator starts during momentary utility
power variations; transfer time delay allows generator set to stabilize before load is
applied; retransfer delay prevents needless power interruption if return of utility power
is momentary; stop delay allows gradual generator set cool down; undervoltage sensing of
utility supply provides reliable starting of generator set during brownout conditions.
2) This switch is not service entrance rated. This generally means that you
need a service entrance rated device between this switch and your utility meter.
3) The standard ZTX contactor comes with 2 power poles to switch the two hot leads
of a 120/240V system. It does NOT switch the neutral, which is acceptable in most
areas of the USA. See article 250.20 of the 2002 NEC. If there are special
requirements in your area that require switching the neutral (as dictated by local codes
or electrical inspectors) you must use the ZTG type transfer switch.
4) Two single pole double throw auxiliary switches (1 on the utility and 1 on the
emergency contactor) are available as an option. These are useful for remote
indication of the switch position or to turn off loads that should not run when on
generator power (such as large heat pumps or central air conditioners). To order use
the drop-down menu below.
5) CAUTION FOR OLD DESIGN SWITCHES - Use care when removing the front cover
of this panel. Loosen but do not remove the four cover screws. Lift cover off
the four screws and hang it on two screws (2 bottom or 2 right-hand). This will
prevent damage to the cable that connects to the keypad on the back of the cover.
This type of damage is not covered under the warranty. This caution does
not apply to new switches that have keypad mounted inside on bracket and
operable through cutout in cover.
6) WIRING - This switch provides a single isolated contact for controlling the
genset. The contact closes when the genset is to start and run.
