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 surge suppressors 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.
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
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.
MacLean's Surge Tec® arresters
are classified for category B and C installations based on the diagram shown below.
The arresters are designed for repeated operation and
Surge arresters provide the path of least resistance
to ground for surges on a power system. The arrestors should
be installed by a licensed electrician.
To provide the best protection, the lead wires should
be kept as short as possible. When 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
For added protection to computers, MacLean Power
a plug-in-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.
Electram stocks both 1-phase and
3-phase Surge-Tec surge arrestors - ideal for installations where
sensitive solid-state equipment is installed
