ZoneSentinel

Engineered specifically for application at distribution boards and small service entrance locations. The ZoneSentinel provides cost effective, high capacity surge protection. When used at a local panel, in combination with a ZoneMaster at the service entrance, ZoneSentinel provides the lowest suppression voltages available today, as well as full protection in all ten modes (L-N, L-G, L-L, and N-G).
