Panelmount (Facility-wide)

Protecting a facility with this parallel line is an excellent first line of defense in limiting high impulse transients to a level that is acceptable to most electronic equipment. These high-energy surge protection products are placed in parallel with panels that are susceptible to both externally and internally generated transients. Our wide range of products offers specific surge protection levels, voltage/phase configurations, and any mode protection requirement at any panel within your facility.

Installing surge protection products at the electrical service entrance is an obvious place to start when needing power protection. However, in most cases, it’s not enough. Installing protection at distribution, branch panel boards, and specific sensitive loads or (Point of Use) equipment throughout your facility is the best way to prevent damage and eliminate associated downtime to sensitive microprocessor-based electronics.

High-speed data links between buildings or one part of a plant to another have become more common with the widespread use of smart transmitters and the increase in unmanned installations. Our surge protection devices are suitable for all process I/O applications with a choice of low resistance units, high bandwidth, and a variety of voltage variants.

Transmitters and sensors are widely used in highly exposed areas, where lightning damage is common. Emerson Network Power’s Signal Line products guard sensitive instrumentation against what we refer to as "back-door" transients.

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.
