DESCRIPTION FEATURES
The SF40 is a multi-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 SF40 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.
