Surge-Trap® Type 1 SPD STT4X Series

Mersen is proud to introduce the new Surge-Trap STT4X: UL Type 1 SPD for outdoor applications! Mersen launched the Surge-Trap STT2 as a low-cost solution to replace antiquated indoor surge protection devices. This SPD soon became very attractive for markets where it could not be used, namely outdoor applications.

Mersen is now offering this SPD with a NEMA 4X enclosure. The new STT4X is electronically identical to the STT2. However, because of its new enclosure, the STT4X is rated for outdoor use.
