Point-of-Use Industrial Surge Protection

Voltage transients can enter an electrical system through utility disturbances, lightning activity, switching equipment, motors and other inductive loads. Even brief surge events can damage sensitive electronic components, cause control system faults and contribute to premature equipment failure.

The STV25K Series is designed to provide an additional level of protection close to sensitive equipment. Installing surge protection at the point of use helps limit the transient voltage that reaches critical controls and electronic devices.

STV25K Surge Protection vs. Tracking Filters

The STV25K Series is designed primarily to suppress damaging voltage transients at the point of use. Applications that also require continuous attenuation of high-frequency electrical noise may be better suited for a SolaHD STFE Elite or STFV Plus tracking filter, which combines surge protection with electrical noise filtering.

Selecting an STV25K Surge Protective Device

When selecting an STV25K device, verify the system voltage, wiring configuration and installation requirements. The surge protective device must be properly matched to the electrical system it will protect. Installation should be completed in accordance with the applicable product instructions and electrical codes.
