STXR120V3Y50N

The Mersen Surge-Trap® Type 1 XR Series (SKU: STXR120V3Y50N) is a high-performance surge protective device (SPD) engineered to meet UL1449 Third Edition standards, providing unparalleled protection for critical electrical systems. Designed as a direct replacement for traditional surge arrestors, this advanced SPD leverages Mersen’s proprietary TPMOV® (Thermal Protected Metal Oxide Varistor) technology to deliver superior safety, reliability, and longevity. The XR Series is specifically optimized for 120/208V 3P Wye systems with N-G mode, making it an ideal solution for industrial, commercial, and institutional applications where consistent power quality is non-negotiable. Surge protection is a critical component in safeguarding sensitive electronic equipment, machinery, and infrastructure from transient voltage spikes caused by lightning strikes, utility switching, or other electrical disturbances. The Surge-Trap® XR Series addresses these risks with a compact, modular design that ensures seamless integration into both new installations and retrofit projects. Its flexible installation options—supporting line or load configurations—allow electrical professionals to deploy it at multiple points in the power distribution network, from the main service entrance to dedicated control panels. This versatility reduces the need for multiple SPD models, simplifying inventory management and lowering total cost of ownership. Mersen’s TPMOV® technology sets the XR Series apart by incorporating thermal protection mechanisms that prevent catastrophic failure under extreme conditions. Unlike conventional varistors, which can overheat and degrade over time, TPMOV® devices are designed to safely disconnect from the circuit in the event of an overload, ensuring continuous protection without risk of fire or equipment damage. This innovation aligns with Mersen’s commitment to delivering products that prioritize both performance and safety, a hallmark of their 150+ years of expertise in electrical protection solutions. The XR Series is particularly well-suited for applications in industries such as manufacturing, data centers, healthcare, telecommunications, and renewable energy, where power quality directly impacts operational efficiency and equipment lifespan. For example, in a manufacturing plant, the XR Series can protect programmable logic controllers (PLCs), motor drives, and variable frequency drives (VFDs) from voltage transients that could otherwise lead to costly downtime. In data centers, it safeguards servers, storage systems, and networking equipment from surges that could disrupt critical operations. Similarly, in healthcare facilities, the XR Series ensures the reliability of life-support systems and diagnostic equipment, where even brief power interruptions can have serious consequences. Installation of the Surge-Trap® XR Series is straightforward, thanks to its modular design and clear labeling for line/load flexibility. Electrical contractors and facility managers appreciate the product’s compliance with UL1449 Third Edition, which provides assurance of rigorous testing and certification. Additionally, Mersen’s global reputation for engineering excellence and customer support ensures that users have access to technical resources, training, and responsive service when needed. Whether deployed in a new construction project or as part of an upgrade to an existing electrical system, the XR Series delivers dependable surge protection that enhances system resilience and extends the life of connected equipment. For professionals tasked with selecting and installing SPDs, the Surge-Trap® XR Series represents a smart investment in long-term reliability. Its combination of advanced technology, flexible deployment options, and manufacturer-backed performance makes it a top choice for protecting investments in critical infrastructure. By choosing Mersen, users gain access to a trusted partner with a proven track record in electrical protection, ensuring peace of mind in even the most demanding environments.
