The XT Series is specifically designed for robust performance in demanding industrial environments. It is ideally suited for 347/600 Volt, 3-phase Wye system configurations, offering comprehensive protection across a wide range of applications. With an impressive surge rating of 200 kA, these devices are capable of absorbing and dissipating massive energy surges, protecting sensitive equipment from lightning strikes, utility switching, and other transient events. The integrated alarm functionality provides immediate notification of device status, allowing for proactive maintenance and minimizing downtime. A key advantage of the Surge-Trap® XT Series is its installation flexibility. Whether installed on the line side or load side of the electrical system, this unit seamlessly integrates into existing infrastructure. This adaptability makes it an excellent choice for a variety of installation points, from the main service entrance of a facility to individual distribution panels and even branch circuits. This comprehensive protection strategy ensures that every level of the power distribution system is shielded against surges. Industries that rely on continuous power and equipment integrity, such as manufacturing plants, data centers, wastewater treatment facilities, and commercial buildings, will find the Mersen Surge-Trap® XT Series to be an indispensable component of their electrical safety strategy. By preventing costly equipment damage, reducing unplanned outages, and ensuring compliance with electrical codes and standards, this SPD contributes directly to operational efficiency and profitability.
