Overview

The Mersen Surge-Trap® Type 1 XR Series, SKU STXR127V1P50, represents the pinnacle of transient voltage surge suppression technology for 127-volt single-phase electrical systems. Engineered to meet and exceed the stringent requirements of UL1449 Third Edition, this Surge Protective Device (SPD) is an indispensable component for safeguarding critical industrial and commercial equipment from damaging voltage spikes. Its advanced design incorporates Mersen's proprietary TPMOV® (Thermal Protected Metal Oxide Varistor) technology, which provides an unparalleled level of safety and reliability. Unlike conventional surge arrestors, TPMOV® technology ensures that the device safely disconnects from the power source in the event of an internal failure, preventing overheating and potential fire hazards. This inherent safety feature makes the XR Series the most secure surge protection solution available on the market today. The compact and versatile design of the Surge-Trap® XR Series offers exceptional installation flexibility. Whether deployed at the main service entrance to protect the entire facility or installed at a specific control panel to safeguard sensitive electronics, its small footprint ensures seamless integration into existing electrical infrastructure. This adaptability makes it an ideal replacement for older, less effective surge arrestors. The blue, poly construction signifies its robust build quality, designed to withstand demanding industrial environments. With a NEMA Type 4X rating, it offers superior protection against dust, water, and corrosion, making it suitable for a wide range of applications, including manufacturing plants, data centers, telecommunications facilities, and commercial buildings. Key features and benefits of the Mersen Surge-Trap® Type 1 XR Series include: * **UL1449 Third Edition Compliance:** Guarantees adherence to the highest industry safety and performance standards for surge protection. * **TPMOV® Technology:** Provides enhanced safety by thermally protecting the device and ensuring safe disconnection during failure events. * **Compact and Versatile Design:** Facilitates easy installation at service entrances or downstream control panels. * **NEMA Type 4X Rating:** Offers robust protection against environmental elements like dust, water, and corrosion. * **127V Single-Phase System Compatibility:** Specifically designed for efficient surge suppression in common single-phase power systems. * **Screw Terminal Connection:** Ensures secure and reliable electrical connections. * **Line or Load Side Mounting:** Offers flexibility in placement within the electrical system. The STXR127V1P50 is a testament to Mersen's commitment to innovation and quality in electrical protection. Professionals seeking a reliable, safe, and high-performance surge suppression solution for their 127V single-phase systems will find the Surge-Trap® XR Series to be an exceptional choice. Its ability to protect against transient voltage surges, coupled with its advanced safety features and flexible installation options, makes it a critical investment for maintaining operational continuity and protecting valuable electrical assets from costly damage.
