-1201 (5/04)

GE Zenith’s ZTG Series switches are built for standard

applications requiring the dependability and ease

of operation found in a power contactor switch.

• Ratings 40 to 3000 amps (2, 3 or 4 poles)

• UL 1008 listed at 480 VAC

•

CSA certified at 600 VAC

(200-260 amp - 480

•

IEC listed at 480V

• Double throw, mechanically interlocked

contactor mechanism

• Electrically operated, mechanically held

• Designed for emergency and standby

applications

• Available in standard (ZTG) or delayed

transition (ZTGD) models

ZTG switches are equipped with GE Zenith’s

next-generation 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 header for network interface

Fully Approved

•

UL, CSA and IEC listed

• Ringing wave immunity per IEEE 472

(

ANSI C37.90A)

• Conducted and Radiated Emissions per

EN55022 Class B (CISPR 11) (Exceeds

EN55011 & MILSTD 461 Class 3)

•

ESD immunity test per EN61000-4-2 (Level 4)

• Radiated

RF, electromagnetic field immunity

test per EN61000-4-3 (ENV50140) 10v/m

• Electrical fast transient/burst immunity test

per EN61000-4-4

• Surge immunity test per EN61000-4-5

IEEE

C62.41 (1.2 X 50ms, 5 & 8 kV)

• Conducted immunity test per

EN61000-4-6

(ENV50141)

• Voltage dips and interruption immunity

EN61000-4-11

Design and Construction Features

• Close differential 3 phase under-voltage

sensing of the normal source—factory

standard setting 90% pickup, 80% dropout

(adjustable); under-frequency sensing

of the normal source factory setting

95% pickup (adjustable)

• Voltage and frequency sensing of the

emergency source—factory standard

setting 90% pickup voltage, 95% pickup

frequency (adjustable)

• Test switch (fast test/load/no load)

to simulate normal source failure—

automatically bypassed should the

emergency source fail

• Type 1 enclosure is standard—also available

in open style or Types 3R, 4 or 12
