FAQs
SP1-240S is purpose-built for 120/240 V split-phase systems and delivers 50 kAIC transient protection, UL 1449 listing, and a compact footprint. It plugs into standard panel layouts without modifying upstream wiring, reducing installation time and the potential for wiring errors. This makes it highly compatible with modern automation cabinets and retrofit projects.
Plan for its 2.5 in depth, 4.8 in height, and 2.9 in width to fit crowded enclosures. Ensure proper clearance for wiring access and heat dissipation, and use appropriately rated conductors and terminations. The device’s 1.25 lb weight minimizes mounting stress on panel rails, simplifying retrofit in existing panels.
Ideal for control panels, PLC racks, servo drives, and machine automation cabinets where surge events threaten uptime. Its 50 kAIC capacity handles high-energy transients from grid switches or switching loads, reducing downtime and extending equipment life in mission-critical automation and data acquisition systems.
The SP1-240S is UL 1449 listed, providing third-party validation of surge protection performance and safety. This certification supports compliance during design reviews, OEM approvals, and field installations, helping ensure market readiness and regulatory alignment across industrial automation projects.
By reducing transient damage to PLCs, drives, and sensors, the SP1-240S lowers maintenance costs and minimizes unplanned downtime. The 2-year warranty further mitigates long-term risk, offering predictable total cost of ownership and faster project payback in panel builds and system expansions.
