Description

The Surge-Trap STXR Series UL listed Type 1 SPD, a leading choice in the STX series, meets the UL1449 5th Edition standards and is an excellent replacement for outdated surge arrestors. This series incorporates TPMOV® technology, ensuring it is one of the safest options available. The STXR series boasts a compact design and offers flexibility for line or load installation, making it ideal for both branch panel and individual equipment protection.

Features

  • The Mersen STXR600D05 is engineered specifically for 600VAC 3-Phase Delta power configurations, providing continuous protection across Line-to-Line (L-L) and Line-to-Ground (L-G) modes. This exact voltage matching eliminates the risk of premature component degradation, ensuring your heavy industrial machinery, motors, and distribution panels are isolated from volatile transient voltage spikes.
  • Featuring industry-leading Thermally Protected Metal Oxide Varistor (TPMOV) technology, this surge protective device (SPD) is internally fused to prevent common catastrophic fail-states such as thermal runaway or arc flashes during an extreme overvoltage event. By isolating the varistor element when it reaches its maximum threshold, it protects your electrical enclosure and eliminates the need for additional upstream overcurrent protection.
  • Classified as a UL 1449 5th Edition Type 1 SPD, this device offers total installation versatility and can be wired on either the line side (before the main disconnect) or the load side of your service equipment. This flexibility streamlines your layout design, allowing electrical contractors to position the unit precisely where protection is needed most—whether safeguarding a main service entrance or an individual branch control panel.
  • Built to handle severe electrical disturbances, the device boasts a robust 50 kA surge capacity per phase and a 20 kA nominal discharge current rating. Backed by a 200 kA Short-Circuit Current Rating (SCCR), it delivers the necessary high-energy capacity to safely suppress large lightning strikes and heavy utility switching transients before they reach sensitive microprocessors.
  • Equipped with a high-visibility, front-facing LED status indicator, maintenance staff can instantly diagnose system health through the clear Lexan cover (Green = Operational, Out = Replace). This immediate visual confirmation minimizes diagnostic downtime and ensures your facility never operates unprotected due to an undetected, spent varistor.
  • The STXR600D05 is fully certified to ANSI/UL 1449 5th Edition standards and CSA C22.2 requirements, ensuring complete compliance with modern electrical safety mandates. Additionally, its alignment with UL96A guidelines makes it a certified component for integrated lightning protection systems, satisfying rigorous building and engineering specifications.
