STC-PoESTC-DRS Series DIN Rail Protection

The Sola STC-DRS Series is a DIN Rail mountable, single pair surge protection module implementing three-stage hybrid technology.
This module addresses over-voltage transients with gas tubes and silicon avalanche components. In addition, sneak currents are mitigated with resetable fuses (PTCs). The PTC increases resistance by several orders of magnitude when over currents exceed safe levels. A normal state resumes when over currents are removed. The ability to self-restore in this manner significantly increases suppressor performance and survivability.

The STC-DRS Series mounts onto a standard 35mm industrial DIN rail. There are three Field Side and three Electronics Side screw terminals. One is reserved for a shield. Three electrically tied ground terminals are provided for grounding the unit to building-approved ground. The shield is isolated from ground.
