DESCRIPTION FEATURES
Designed for installation at a branch panel, the SF120 is a serious business, heavy duty protector. This cost conscious unit provides protection without the usual frills. A rugged unit that guards critical areas of a facility from the destructive effects of transients originating from both internal and/or external sources.

The SF120 employs multiple-fused surge current paths with built-in redundancy to ensure the most effective method of transient overvoltage dissipation. In addition, each phase is monitored by 2 Green LED protection present indicators.
