September 25, 2017 — Mersen has upgraded its Surge-Trap Pluggable (STP) Series of surge protective devices (SPDs). The new STP series is DIN-rail mountable and improves overvoltage protection for DIN-Rail applications, the company says.

Featuring a 7kA surge capacity rating, a fail-safe self-protected design, visual indicator, and a small footprint, the product uses Mersen’s TPMOV technology. It also includes optional remote indication and an expanded wire gauge range from 4-14 AWG.

MIL-STD-810E vibration tested and UL 1449 4th Edition approved, the new STP series has a high short circuit rating and a thermally protected MOV, which “eliminates the need for additional overcurrent protection devices.”
