SPC
The SPC120240H1P delivers a 120 kAIC interrupt rating, enabling it to absorb and interrupt high-energy surges before they reach sensitive equipment. This directly reduces repair costs and unplanned downtime in facilities with heavy motors and drives. In practice, the device protects motor controllers, PLCs, and sensors on 240V delta networks, boosting system reliability in demanding environments. With a 240V delta (4W+G) voltage rating, the SPD clamps surges effectively across four conductors, ensuring consistent protection for critical loads and simplifying engineering controls for downstream equipment. The rugged NEMA 4X enclosure supports outdoor and washdown installations, eliminating the need for extra enclosures and reducing overall installation costs. External side mounting offers installation flexibility, enabling quick retrofits in existing switchgear or panels. A 10-year warranty and UL 1449 certification further improve total cost of ownership by delivering long-term protection with predictable service life. Standard configuration ensures seamless compatibility within the SPC series ecosystem, minimizing integration time and helping facilities scale protection across multiple lines for greater operational resilience.
