ZTG switches are equipped with GE’s Zenith
MX150 microprocessor panel, which controls
the operation and displays the status of the
transfer switch’s position, timers and available
sources. As an embedded digital controller,
the MX150 offers high reliability and ease of
unattended operation across a range of
applications. The MX150 features include:
• Timer and voltage/frequency settings
adjustable without disconnection from
the power section
• Built-in diagnostics with an LCD display
for immediate troubleshooting
• LED/LCD indicators for ease of viewing
and long life
• Nonvolatile memory—clock battery backup
not required for standard switch operation
• Processor and digital circuitry isolated
from line voltage
• Inputs optoisolated for high electrical
immunity to transients and noise
• Communications network interface
• Conducted and Radiated Emissions per
EN55022 Class B (CISPR 22) (Exceeds
EN55011 & MILSTD 461 Class 3)
• ESD immunity test per EN61000-4-2

Design and Construction Features
• Close differential 3 phase under-voltage
sensing of Source 1 (normal)—factory
standard setting 90% pickup, 80%
dropout (adjustable); under-frequency
sensing of Source 1 factory setting
95% pickup (adjustable)
• Voltage and frequency sensing of the
Source 2 (emergency)—factory standard
setting 90% pickup voltage, 95% pickup
frequency (adjustable)
• Test switch (fast test/load/no load) to
simulate Source 1 (normal) failure—
automatically bypassed should the
Source 2 (emergency) fail
• NEMA Type 1 enclosure is standard—
also available in open style or NEMA
Types 3R, 4, 4X or 12

Delayed Transition
Switch Types
• Standard: Unless otherwise noted, the
standard switch with quick transfer will
be supplied.
• Delayed Transition: When ordered as
the ZTGD, the delayed transition switch
offers time delay during transfer from
one position to the other. This is primarily
for transfer of large motor or inductive
loads. The operation of the delayed
transition switch is totally independent
of the synchronism of the power sources,
eliminating the need for in-phase monitors
or extensive motor-disconnect control
wiring between the transfer switch and
motor control centers.
