Overview

The Mersen Surge-Trap® Type 1 XT Series model STXT01S2004XA delivers advanced surge protection for 120/240V split-phase electrical systems. Engineered with Mersen’s proprietary TPMOV® (Thermally Protected Metal Oxide Varistor) technology, this Type 1 Surge Protective Device (SPD) ensures superior thermal protection and fail-safe operation, minimizing catastrophic failure risks. The unit features a 200 kA Short-Circuit Current Rating (SCCR) per phase, making it capable of handling extreme transient events such as lightning strikes and utility switching surges. With a 20 kA nominal discharge current and UL 1449 Fourth Edition listing, the STXT01S2004XA meets stringent safety standards for service entrance, distribution, and branch panel applications. Its NEMA 4X polycarbonate enclosure provides corrosion resistance and watertight protection, ideal for harsh industrial environments. The device supports both line-side and load-side installation, offering flexibility in system design. Additional features include phase-loss monitoring, EMI/RFI filtering up to -50dB (10kHz–100MHz), and a wide operating temperature range of -40°C to +85°C. Wiring is field-wired with #8–10 AWG conductors. Applications include service entrances, AC distribution, power supplies, drive protection, large control panels, telecommunications, and IT/data centers. The STXT01S2004XA is a reliable solution for protecting sensitive electronic equipment, motor controls, and automation systems from transient overvoltages, reducing equipment damage, data loss, and operational disruptions.
