Surge Protection

Mersen’s Surge-Trap® STLC surge protective device adds a critical layer of surge protection for your entire home. TThe STLC series can be installed in minutes, and is unique in that it has been designed and tested to fit in a variety of load centers from multiple manufacturers. The STLC Series is designed with Mersen’s TPMOV® technology to ensure superior safety and reliability. Listed UL 1449 5th Edition Type 1 SPD and satisfies latest NEC requirement for surge protection for residential dwellings.

Mersen’s TPMOV technology eliminates common failure modes that occur in the field with standard metal oxide varistors. Internally each unit is comprised of a voltage clamping device and a disconnecting apparatus that monitors the status of the metal oxide disk, making the TPMOV surge suppression component a fail-safe device. In the event of an overvoltage breakdown, the metal oxide disc is securely disconnected from the system power by an arc shield. Upon failure, the TPMOV surge suppression component is also equipped with a visual pin indicator as well as a normally open micro-switch, providing remote indication if applicable.

TPMOV7 series surge suppression component: 50% more surge capacity, in the same footprint
The TPMOV7 series is rated for 75kA - 8/20μs peak surge current and is available for maximum continuous operating voltages (MCOV) from 150V to 320VAC.

The Surge-Trap Type 1 STXP Series offers a balance of redundant surge protection in a compact form factor with flexible installation options. Catalog numbers in this series can be panel mounted, side mounted,and have a separate optional flush mount cover. Additionally, the STXP series has options for remote indication and comes standard with LED indication on each phase. The STXP series incorporates TPMOV® technology for maximum safety and does not require additional overcurrent protection. Suitable for installation on both the line and load side of a panel, the STXP is ideal for everything from service entrances to machine-specific control panels.
