Panel Mounted

Protecting a facility with this SPD parallel line is an excellent first line of defense in limiting high impulse transients to a level that is acceptable to most electronic equipment.

Plug In

The plug-in construction makes these SPD products ideal for easily protecting sensitive home or office equipment within harsh environments, including TVs, home theaters, satellite dishes, computers, printers, copiers, and fax machines.

Telecommunication lines are widely used in highly exposed areas, or in long runs between buildings. Left unprotected at the primary and secondary, the conductors used in telecommunication applications are highly susceptible to transient impulses. Our telecom surge protection products are suitable for primary, secondary, and security applications.
