The optional ASCO

5500 Thin Web Server

provides Web-enabled

control.

An operator or

supervisor can monitor

various transfer switch,

engine and generator

parameters remotely using

the Thin Web Server.

The server provides

real time access and control

of critical power system

performance.

Users can manage,

check system status and

recognize potential system

failure.

It requires no dedicated

hardware or software

to operate and can be

connected to any standard

PC with a Microsoft

Internet Explorer browser.

E-mail and text paging

features alert users of

abnormal conditions.

Communication Products

Generator Breakers

Generator circuit

breakers offer drawout

convenience to simplify

maintenance or

replacement.

Electrically-operated

front-serviceable drawout

breakers are available in

800 amp to 3000 amp

frame sizes.The Square D,

NW, 5.0P insulated case

circuit breakers are UL 489

listed and are included with

an adjustable long time

delay, short time delay,

instantaneous overcurrent

trip and ground fault alarm.

Additional features

include 120VAC electrical

operation, 24 VDC shunt

trip, bell alarm, 4a and

4b auxiliary contacts, a

protective cover for the

manual close pushbutton,

and instantaneous and

ground fault indications.

Square D Micrologic

5.0P Trip units provide

monitoring of electrical

parameters as well as visual

indication. Trip settings

are adjustable from 40 %

to 100% of the generator

breaker frame size and

a Modbus

RTU port

provides communications

to the Emergency Power

Communication System.

An ASCO 5110 communi-

cation module also available

with only RS485 communi-

cations for monitoring and

control with ASCO Power-

Quest

systems.

The ASCO 5350 Power

Transfer Switch Remote

Annunciator is a stand-

alone, industrial grade

interface device providing

you with the most critical

transfer switch status

indication and transfer/

retransfer control for up to

eight switches. Ethernet

technology is built in for

faster and more reliable

communications. LEDs

indicate switch status

and position, while

separate push buttons

individually initiate transfer

switch operation and

testing. Transfer switch

annunciators can be set

up in multiple locations to

monitor various transfer

switches, allowing

redundant and distributed

annunciation.
