Overview

The Mersen Surge-Trap® Type 1 XT Series (SKU: STXT07S1004X) represents the pinnacle of advanced surge protection technology for critical industrial and commercial electrical systems. Engineered with Mersen's proprietary TPMOV® (Thermal Protected Metal Oxide Varistor) technology, this surge protective device (SPD) offers unparalleled safety and reliability, setting a new standard for transient voltage suppression. The XT Series is designed to safeguard sensitive equipment from damaging voltage surges, ensuring operational continuity and protecting valuable assets. This Type 1 SPD is exceptionally versatile, featuring flexible installation options on either the line or load side. This adaptability makes it an ideal solution for a wide range of applications, from the main service entrance of a facility all the way down to individual distribution and branch panels. Its robust design and advanced protection capabilities make it a crucial component in maintaining the integrity of electrical infrastructure in demanding environments. The Mersen Surge-Trap® XT Series is specifically designed for 220/380 Volt, 3-Phase Wye (3P Wye) system configurations. This voltage and system type are common in many industrial settings, power distribution networks, and large commercial buildings. By effectively clamping transient overvoltages, the XT Series prevents surges from reaching and damaging sensitive downstream equipment such as motors, control systems, PLCs, computers, and lighting. Key benefits and features of the Surge-Trap® Type 1 XT Series include: * **Advanced TPMOV® Technology:** Provides superior thermal protection and fail-safe operation, significantly reducing the risk of thermal runaway and fire. * **Type 1 SPD Rating:** Designed for installation at the service entrance or on the load side of the main overcurrent protective device, offering comprehensive protection. * **Flexible Installation:** Can be installed on either the line or load side, simplifying integration into existing or new electrical systems. * **Wide Application Range:** Suitable for service entrances, distribution panels, sub-panels, and branch circuits. * **220/380V 3P Wye System Compatibility:** Engineered for specific industrial voltage and system configurations. * **Enhanced Safety:** The integrated TPMOV® technology ensures that if a varistor fails, it disconnects safely from the circuit without compromising the power supply. * **Mersen Quality:** Backed by Mersen's extensive experience and reputation in electrical protection solutions. Protecting your electrical infrastructure from the unpredictable nature of transient surges is paramount. The Mersen Surge-Trap® Type 1 XT Series, with its cutting-edge TPMOV® technology and flexible design, offers the ultimate solution for ensuring the safety, reliability, and longevity of your critical electrical systems. Invest in the safest and most advanced surge protection available for your 220/380V 3P Wye applications.
