FAQs
SPD100240H2K is Eaton’s external-side-mount surge protection device for 240V delta (4W+G) systems. It provides 100 kAIC protection and UL 1449 listing to shield downstream equipment such as drives and PLCs from transient overvoltages. Ideal for control panels and switchgear, it fits standard indoor enclosures with straightforward retrofits.
Install SPD100240H2K by mounting the unit to the outside of existing electrical distribution equipment (external side) in a NEMA 1 enclosure. Use the included brackets and hardware, and connect to line and load terminals per the installation manual IM01005031E. Confirm wiring for 150 L-N, 150 L-G, 150 N-G, and 300 L-L voltages.
Yes. SPD100240H2K is designed for 240V delta high-leg (4W+G) systems and provides protection across L-N, L-G, N-G, and L-L voltages. Its 100 kAIC rating ensures resilience against large surges, while the external mounting remains practical for demanding manufacturing environments.
SPD100240H2K carries UL 1449 listing, indicating compliance with recognized surge protection safety standards. It features a NEMA 1 indoor enclosure and is backed by a 15-year warranty, supporting long-term reliability, safety, and procurement confidence in industrial environments.
Expect a favorable ROI from reduced downtime and extended downstream equipment life due to robust surge protection. The 100 kAIC capacity handles large transients, while the 15-year warranty and straightforward external mounting simplify maintenance planning and lifecycle cost control for facilities with frequent surge exposure.
