Split-phase 120/240 V input design provides broad compatibility across most distribution panels. This reduces engineering time and simplifies wiring, letting the SPC120240S3P protect two hot legs with a common neutral for diverse applications such as control panels and switchgear. A high 120 kAIC interrupt rating absorbs surge energy and prevents downstream damage, supporting continuous operation of motors, drives, and PLCs during transient events. NEMA 4X enclosure delivers rugged protection against dust, water splash, and harsh environments, enabling installation in manufacturing floors, outdoor enclosures, or damp areas without extra housing and reducing maintenance concerns. The audible alarm provides immediate status feedback, enabling quick fault identification and improved maintenance planning, while still allowing normal operation with minimal downtime. External side mounting simplifies retrofit and installation in tight spaces, avoiding intrusive chassis work and speeding up upgrades. The combination of UL 1449 certification and a compact footprint supports scalable deployment across multiple panels while delivering demonstrable ROI through reduced downtime and extended equipment life.
