HA/JA Hard-Wired Panel Protection Units

The HA and JA Series surge protection devices protect your sensitive electronic equipment and systems from external or internal transient sources. Suppress external surges with one of these surge protectors mounted at the main service panel. Place these units at branch panels or at specific pieces of sensitive equipment to provide area or point-of-use protection.

The latest in SuperPath and MOV technology diverts and dissipates the bulk of a spike so "let through" to sensitive electronics is minimized. These surge protectors are ideal for smaller applications - small networks in particular. You get superior protection in a compact economical package.
