FAQs
SPD100240H2N supports external sidemount installation, enabling the unit to be mounted on the side of distribution equipment without modifying existing enclosures. This simplifies retrofits, reduces installation footprint, and speeds up upgrades in control panels or switchgear. The sidemount approach also streamlines service access for maintenance checks and replacements, minimizing downtime during protection upgrades.
A 100 kAIC interrupt rating means the SPD can safely interrupt high-energy surge events before they reach downstream components like motors and PLCs. This reduces the risk of arc flash, insulation damage, and control faults. In practice, it translates to improved uptime, fewer unplanned outages, and longer service life for critical automation hardware in demanding manufacturing environments.
Yes. The SPD100240H2N is designed for 240V delta (4W+G) systems and comes in a rugged NEMA 4X enclosure, making it suitable for outdoor and harsh indoor environments. External sidemount installation further supports outdoor integration, allowing protection to be deployed without compromising weather resistance or panel integrity.
This unit carries UL 1449 certification, a critical safety standard for surge protection devices. While CE, SIL, and IP ratings are not listed for this model, the NEMA 4X enclosure provides robust environmental protection. Always verify local electrical codes and perform site-specific hazard assessments to ensure full compliance with your facility’s protection strategy.
ROI is driven by reduced downtime, fewer equipment repairs from surge events, and lower maintenance costs over the system’s life. The 15-year warranty simplifies budgeting and replacement planning, while external sidemount installation minimizes installation time and service disruption during protection upgrades. In high-surge environments, this translates to faster payback through improved line reliability.
