SolaHD STV100K Series Hardwired Surge Protective Devices products protect electrical or signal circuits from transient overvoltage events that can damage controls, communication equipment and other sensitive electronics.
SolaHD uses different surge families for service-entrance and branch-panel AC power, DIN-rail control applications, point-of-use filtering and data/signal circuits. The protection device must match the circuit type and system voltage it is installed on.
Selection should verify nominal voltage and wiring configuration, installation location, surge-current capability, connection method, protected modes, circuit or signal type and any required monitoring or status indication.
Facility surge protection is most effective when coordinated in layers from the service entrance to branch panels and sensitive loads. A device intended for AC power should not be substituted for a data/signal protector, and signal protectors must match the communication circuit and connector or terminal format.
For AC devices, verify the exact system configuration - such as single-phase, split-phase, wye or delta - because the catalog number is tied to the voltage and wiring arrangement. Keep surge-device conductors as short and direct as practical in the installation.
For STC and other signal-line products, confirm the protected interface, signal voltage and grounding method to avoid degrading the communication circuit.
SolaHD recommends coordinated protection at appropriate facility levels, including service entrance, branch panels and sensitive loads, with dedicated products for AC power and data/signal circuits.
No. System configuration, installation location, surge rating, circuit type and connection method also need to match the application.
