Today's sophisticated electronic equipment requires reliable, surge protective devices. By selecting Joslyn
life for your equipment.
The ServiceTrack surge protective device connects to your electrical distribution system to protect sensitive electrical
and electronic equipment against the harmful effects of lightning strikes, induced transients on AC power lines, internally
generated transients and high-frequency noise. ServiceTrack fulfills the single-pulse surge current capacity testing
recommendations per NEMA LS1-1992, paragraphs 2.2.9 and 3.9.
ServiceTrack provides advanced surge protection and filtering technology. Created for optimum reliability and flexibility,
ServiceTrack offers unrivaled protection and features in a modular, building-block design with a choice of four types of
suppression modules: Metal Oxide Varistor (MOV); Silicon Avalanche Diode (SAD); and High-Frequency Filter. This innova-
tive modularity allows simple and quick maintenance procedures should a module need to be replaced. Each suppression and
filter module has an at-a-glance, bicolor status light (green = healthy and red = fault) to confirm the individual elements of
the suppressor system are functioning properly. In addition, each module has a keyed mounting as well as color-coded labels
to ensure correct module replacement:
ServiceTrack's unique design provides true, fail-safe protection. An individual thermal cut-off on each MOV and SAD
protects against temporary overvoltage, limited short circuit current conditions and ensures clean end-of-life performance.
MOV module has 20kA backup MOVs to provide continuous protection.
ServiceTrack offers a full range of monitoring options. Choices range from the basic commercial-power and suppressor-status
indicator lights with Form C dry relay contacts, to the full-featured package, featuring audible alarm with disable switch and
surge event counter.
ServiceTrack's robust NEMA 4/4X enclosure allows installation in outdoor and corrosive environments.
Improper installation or misapplication may result in serious personnel injury and/or damage to electrical system.
Read the complete installation instructions before proceeding with installation. Remove all power to the electrical
panel before installing or servicing the suppressor.
All work must be performed by licensed and qualified personnel. The electrical system must be properly grounded in
accordance with the U.S. National Electrical Code, state and local codes or other applicable codes for this suppressor
to function properly. Do not connect ServiceTrack to the line side of the main service breaker or disconnecting means.
Do not install the suppressor where the available short circuit current to ServiceTrack is more than 100,000 RMS
symmetrical amperes at 480VAC.
