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
