| DESCRIPTION |
FEATURES |
| The SPA3.5, is a
single phase, shunt installed protector for use at a single piece of sensitive
electronics, or at a local branch distribution panel. This compact but exceptionally
capable surge suppressor offers rock-solid protection for specific, critical areas. The SPA3.5 provides full size performance in a small package.
Designed with brute force MOVs, this low profile unit enables installation where
substantial protection is needed, cost is critical and space may be limited. Bi-polar and
bi-directional protection eliminates a transient from coupling through a common panel from
another room.
