SURGE TEC Secondary Arresters
installed properly, they will divert lightning surges to ground
very quickly. Surge Tec arresters offer the first line of defense
for the entire electrical service and protect wiring, major
appliances, pumps, and heating/air conditioning equipment.
For added protection to computers, Joslyn recommends plugin-strip type of device with lower clamping voltages as a
second line of defense. This type of coordination provides
excellent surge protection for the entire electric service.
FEATURES
Electricity users, from the homeowner to big business, are
more interested today in the quality of the power they
receive than in the past, and with good reason. Advances in
technology have introduced new electronic equipment and
appliances that are more susceptible to damage by power
surges. Replacing or repairing damaged equipment is
inconvenient and can be costly.
Lightning or an interruption in the power line can generate
a power surge. These high energy surges can enter a home
or building through the electric service entrance. Once the
surge enters the building, there is a possibility that high
voltages resulting from the surge current will damage
electrical wiring or equipment. Surge Tec arresters are
designed to limit surge voltages by discharging (bypassing)
surge current to ground.
Individuals should assess their risk by evaluating the potential
impact that a power surge may have on their property. In
many cases, the cost of protection is relatively inexpensive
compared to the possible loss. The Surge Tec arrester is
designed to provide brute force protection against surges at
the service entrance, where protection is needed the most.
The family of Surge Tec arresters provides an excellent first
line of defense for any critical electrical service, whether it
is in a home, business or industrial applications.
SURGE ARRESTER APPLICATION
Joslyn’s Surge Tec arresters are classified for category B
and C installations based on the diagram shown on page
AR-9. The arresters are designed for repeated operation and
continuous protection.
Surge arresters provide the path of least resistance to ground
for surges on a system. THE ARRESTERS SHOULD BE INSTALLED
BY A LICENSED ELECTRICIAN. To provide the best protection,
the lead wires should be kept as short as possible. When
Surge Tec arresters incorporate special features that make
them stand above other Secondary Arresters and Transient
Voltage Surge Suppressors (TVSS). These arresters use a
patented (#5,502,612) fault withstand design along with
replacement indication. The arresters are available in 175
volt, 480 volt and 650 volt AC ratings for application on
system voltages below 650 volts phase to ground and
operate at frequencies between 48 and 62 Hz. The units
come with 18 inch, #14 AWG solid copper wire leads and
are designed to be mounted outdoors or indoors.
• METAL OXIDE VARISTORS—Surge Tec arresters use Joslyn
manufactured metal oxide varistors (MOV). This takes
advantage of our experience with metal oxide production
for the utility industry. The arresters meet ANSI/IEEE
C62.11-1993 for secondary arresters. In addition, they
have passed a 5kA Duty Cycle test. They provide high
speed response and excellent energy capability for today’s
critical electric loads.
• REPLACEMENT INDICATION—A visual indication on the
front label permits routine checks of the arrester’s
operational status. Indication windows on the label turn
black if the arrester fails. The arrester should be replaced
when any area of any window turns black.
• FAULT WITHSTAND CAPABILITY—Surge Tec secondary
arresters’ patented design achieves a fault withstand
capability of 10kA rms without the use of any external
fusing. This unique design has been tested at high current
failure modes to verify its ability to withstand a failure
without a violent fracture of its housing. Fault current is
the full available current that the device conducts in the
event it is short circuited by conducting a surge beyond
the designed capability. This provides significant
advantages in the area of secondary voltage protection.
• COST EFFECTIVE—The Surge Tec arresters are very
inexpensive compared to potential equipment damage.
• UL and UL CANADA LISTING—The UL listing as a
secondary surge arrester for AC applications provides
assurance of the Surge Tec quality surge arrester design.
• JOSLYN GUARANTEE—A one (1) year warranty is provided
on all products manufactured.

SURGE TEC Secondary Arresters (continued)
FAULT CURRENT WITHSTAND CHARACTERISTICS
The SURGE TEC secondary arresters have a patented fault
withstand design. This unique design has been tested at high
current failure modes to verify its ability to withstand a
failure without a violent fracture of the housing. Fault
current is the full available system current that the device
conducts in the event it is short circuited by conducting a
surge beyond the designed capability. This provides significant advantages in the area of secondary voltage protection.
There currently is not a standard requirement or test
specification for fault withstand capability of secondary
arresters. The SURGE TEC arresters were tested by falling
them with an overvoltage and then applying fault currents
of 4kA and 10kA. The arresters achieved the fault withstand
capability of 10kA rms without the use of, or the
requirement for, any external fusing. The result is a highly
reliable metal oxide secondary arrester with additional
benefits that until now had not been available.

EXPULSION TYPE SECONDARY SURGE ARRESTERS
Features
Housing – Made of high intensity Bakelite; excellent
mechanical and electrical strength; flame retardant. The
perforated screen safely guards against flying particles
during venting of the gases.
Expulsion Chamber – Surge current capability is increased
and discharge voltage minimized because no resistor blocks
are used. Deionizing gas generated by the fiber discs acts to
extinguish the power follow arc.
Lead Wires – The J9200-1 uses No. 10 AWG, 19 strand,
tinned copper lead wires. The leads and twelve inches long
and have PVC insulation with 105°C continuous temperature
strength and 600 volt insulation strength.
Electrical Characteristics
Application
Expulsion type secondary surge arresters, J9200-1, are
designed for protection of 2-pole, 3-wire 120/240 volt
electrical service. They must be installed outdoors or in a
completely sealed enclosure. The expulsion type design
enables these arresters to handle very high surge currents
while maintaining the discharge voltage at very low levels.
Protection of the farm or home electrical systems,
submersible water well pump motors and security lights are
typical applications.
