Surge Protection

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.

570 Surge Protective Device (formerly Liebert SH)
A true hybrid device offering a coordinated multi-stage system of suppression, integrating the fast response time of the SAD (Silicon Avalanche Diode) modules with the high-energy capability of the MOV modules. S
