UL Control Panel Shop finds asource for reliable, cost-effective
products in one catalog
CASE STUDYSituation
A Georgia UL508-698A control panel shop prides itself on
giving its customers products of the highest quality - pumpcontrol panels built to last. Their primary focus is on pumpcontrol panels for water and wastewater pumping systems,including lift stations, booster stations, stormwater stations,and more. Their business growth over the years can be
attributed to creating loyal customers who come back again
and again. What keeps them coming back? First and foremost,they pride themselves on providing superior customer service.
Additionally, the components used in their panels are chosen
for their reputation of working as advertised with very few
failures, and they are cost competitive so their customers geta good deal for their money.
Rick, the Senior Electrical Engineer for the company, plays alarge part in choosing their component vendors, and ensuring
they meet those criteria. Rick states, “We ship panels all over
the US and beyond, and if a component fails then our panel
has failed - and our name is right there on the front door ofthe panel.”Several years ago, Rick began using products manufactured
by SymCom, and has stuck with them ever since. Rickcomments, “At one time or another we have used almost
everything in that catalog. If a spec calls for a component
with a definite purpose, we look in the SymCom catalog
first.” With the majority of the project specifications they see
calling for pump protection and control components such as
UL overload relays, phase monitors, alternating relays, seal
leak detectors, and intrinsically safe switches, it is of great
benefit to be able to source all of these from one vendor. And
while he’s able to buy these very competitively cost-wise,

price isn’t the bottom line for Rick. “Choosing components thatare cost effective because they last, rather than looking to savea couple of bucks and then dealing with the service work andreplacements because they fail, saves us money in the long run.”“If a spec calls for a component witha definite purpose, we look in theSymCom catalog first.”
Some of the SymCom products frequently used by this UL
Panel Shop include the 777 3-Phase Current & Voltage
Monitor (including several unique variations of it for enhanced
functionality), the 77C Single-Phase Current & Voltage Monitor,
the 460 voltage/phase monitor, the ISS101 Intrinsically Safe
(IS) Switches, the ALT series alternating relays, and thePC102-CICI-LT seal-leak and over-temp monitor. Other products
often used by UL panel shops include a variety of phase orvoltage monitors, IS and Non-IS pump controllers for up to 4SymCom.com© October 2015 Littelfuse Protection Relays & Controls

Rick chooses the 777 MotorSaver ® or 777-KW/HP PumpSaver ®
when possible as it gives him an advanced motor protection
device that provides a UL overload relay and voltage/phase
monitor, as well as additional functionality his customers
appreciate such as underload and ground fault protection, an
on-board display for viewing real-time voltage and current perphase, and optional communications to SCADA via several
choices of protocol. If a water or wastewater municipalityalready has a SCADA system, and is already planning on
getting data from a remote pumping station, it’s very easy forthem to tie in communications from 777s, giving them all thereal-time electrical data as well as notification and cause oftrips. Knowing not only that a pump motor has tripped, but thecause, can help users determine if a service tech must be sentout immediately or not - saving time, money and frustration.

us money in the long run.”
One additional benefit Rick gets by choosing SymCom products
is, he states, “During inspections the UL rep can clearly see
the UL markings on the SymCom device.” He noted that “Manyother component manufacturers place the markings so that theUL rep has to dig around in the panel looking for the marking.
That makes for a long and difficult inspection.” Most UL panelbuilders would agree - the sooner they can get inspectors out
the door, the sooner they can get back to business. This panel
shop has found a trusted source of multiple components in
SymCom, and plans to continue using them for years to come.
