Overview

Protect your critical electrical infrastructure with the Mersen Surge-Trap® Type 1 XR Series Surge Protective Device (SPD), SKU: STXR240V1P50. Engineered to meet the stringent requirements of UL1449 Third Edition, this advanced SPD is the definitive solution for safeguarding 240V single-phase systems against damaging transient voltage surges. At the core of the XR Series lies Mersen's proprietary TPMOV® (Thermal Protected Metal Oxide Varistor) technology, setting a new benchmark for safety and reliability in surge protection. This integrated thermal disconnect mechanism ensures that the device safely disconnects from the power line in the event of internal failure, preventing overheating and potential fire hazards, making it the safest SPD available on the market. The Surge-Trap® XR Series is designed for unparalleled installation flexibility. Its compact, space-saving footprint allows for seamless integration into a wide range of electrical panels and systems. Whether deployed at the service entrance to provide whole-building protection or installed at a specific control panel to safeguard sensitive equipment, the XR Series offers a versatile and effective surge suppression solution. This adaptability makes it an ideal choice for various industrial, commercial, and even advanced residential applications where reliable power quality is paramount. Key features and benefits of the Mersen Surge-Trap® Type 1 XR Series include: * **UL1449 Third Edition Compliance:** Ensures adherence to the highest industry safety and performance standards. * **TPMOV® Technology:** Provides inherent thermal protection and enhanced safety, preventing catastrophic failure. * **Compact Design:** Facilitates easy installation in tight spaces, suitable for both line and load side connections. * **Versatile Application:** Ideal for service entrances, sub-panels, and critical equipment protection in 240V single-phase systems. * **High Reliability:** Built with Mersen's commitment to quality and durability, ensuring long-term operational integrity. In industrial environments, where sensitive automation equipment, variable frequency drives (VFDs), and programmable logic controllers (PLCs) are commonplace, voltage transients from lightning strikes, utility switching, or internal motor operations can cause significant downtime and costly repairs.
