SRA64C-008 Surge Protector.
The Emerson Edco SRA64C-008 surge suppressor is a single pair 2 wire cube surge protection implementing three-stage hybrid technology.
The SRA64C-008 addresses over voltage transients with gas discharge 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 over-currents 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 Edco SRA64 second stage clamps are placed from each signal line-to ground. In certain cases, where ground potentials vary from site-to-site, a line-to-line only second stage clamp may be preferred. This variation is specified by a suffix "D" on the part number. In other cases, line-to-line and line-to-ground second stage clamps may be preferred. This variation uses an "X" suffix on the part number.
A variety of clamping voltages are available as standard. Reference the “How to Specify the Appropriate Model” section to insure that a complete part number description is obtained.
