Overview
The SolaHD STV 200/400K Series are surge protective devices designed to provide continuous protection from voltage transients and electrical noise at service entrances or distribution panels. Their modular design allows for flexible installation, and they are robust enough for severe exposure locations.

Specifications
The devices utilize patented circuitry to monitor protection modes, including neutral to ground. They feature LED indicators for status and high isolation form C dry contacts for remote monitoring. They meet UL 1449 (second edition), UL 1283, and cUL standards, and are ANSI/IEEE tested for various categories. The devices are available in hardwire, three-phase configurations and are designed for long-term, trouble-free operation.
