Description
The SL1026 Series is a heavy-duty transient
suppresser using Gas Plasma technology. In
response to transients that exceed the device's
breakover voltage, the device changes from a very
high impedance state to a low impedance state to
conduct harmful current away from the protected
system. The SL1026 is designed to protect electrical
and electronic equipment such as communications,
control and railway systems. Carefully designed
geometry ensures against short circuiting if a failure
occurs due to conditions and events beyond the
design criteria. Optional electrical mounting clip (part
SL1053 ) is available to aid mounting and connection.
Features
• RoHS compliant
• 55 kA surge capability
(single shot) tested with
8/20μS pulse as defined
by IEC 61000-4-5
• 40 kA surge capability
(repetitive)
• Will protect against
Trapezoidal waveforms
as specified in RIA 12.
• Will protect against
capacitor discharge
voltage transient
waveforms as specified
in RIA 12.
• Will protect against
double exponential
voltage transient
waveforms as specified
in IEC 571.
Applications
• Signaling equipment.
• Communication
equipment
• Control gear.
• Trackside cabinets.
• Cell phone base
stations
