ASCO Model 142 Installation Manual

Series 100
Model 142 (Edco SRA64 Series)
1 Pair Data/Signal
Surge Protective Device
Technical Documentation
The ASCO Model 142 surge suppressor is a single pair
cube implementing three-stage hybrid technology. This
cube addresses over voltage transients with gas tubes and
silicon avalanche components. In addition, sneak and fault
currents are mitigated with resettable fuses (PTCs). The PTCs
increase resistance several orders of magnitude when overcurrents exceed safe levels. A normal state resumes when
over-currents are removed. The ability to self restore in this
manner significantly increases suppressor performance and
survivability.
The standard Model 142 second stage clamps are placed from each signal line-to
ground. In certain cases, where ground potentials vary from site-to-site, a line-toline only second stage clamp may be preferred. This variation uses an “X” in position
12 of the model number. In other cases, line-to-line and line-to-ground second stage
clamps may be preferred. This variation uses an “X” in position 12 of the part number.
A variety of clamping voltages are available as standard. Reference the “Ordering
Information” section to insure that a complete part number and description is
obtained.
