Eaton SPD100240H1K Surge Protection Device - UL 1449
Part Number: SPD100240H1K
Quick Summary
The Eaton SPD100240H1K surge protection device protects electrical systems from transient spikes in industrial control panels and distribution equipment. Too often, uncontrolled surges damage sensitive drives, trigger unplanned downtime, and drive maintenance costs higher. UL 1449 listed, with a rugged NEMA 1 enclosure, offers reliable protection in indoor control cabinets while the 100 kAIC interrupt rating handles large transient events. External side mounting simplifies retrofit work and rapid serviceability. Designed for 240V delta high-leg configurations, it provides robust L-N, L-G, N-G, and L-L protection, supporting longer asset life and predictable maintenance budgets. This SPD integrates smoothly into existing protection schemes and reinforces a practical path to lower total cost of ownership.

FAQs
SPD100240H1K is designed for external side mounting to simplify retrofits. Install on a compatible distribution panel or enclosure with accessible space for the 9.5 inch depth and the 5.4 inch width. Ensure proper clearance for venting and service access, secure mounting to the external surface, and connect L-N, L-G, N-G, and L-L conductors per the wiring diagram in the installation manual.
Key specs include 100 kAIC interrupt rating for high-energy transients, 240V delta (4W+G) rating, and operating voltages of 150 L-N, 150 L-G, 150 N-G, and 300 L-L. It’s UL 1449 listed and designed for internal, indoor use with a NEMA 1 enclosure, supporting reliable protection for control panels and drives.
Yes. Its NEMA 1 indoor enclosure, external side mounting, and 100 kAIC capability make it appropriate for control cabinets, motor control centers, and production line distributions. The device protects critical loads such as PLCs, drives, and sensors from transient surges common in factory settings, helping reduce downtime and maintenance costs.
The SPD100240H1K carries UL 1449 listing for surge protection devices, indicating compliance with industry safety and performance standards. It also features a 15-year warranty, reinforcing long-term reliability and reducing lifecycle risk for procurement teams evaluating total cost of ownership.
By absorbing damaging transient energy and preventing premature equipment wear, the SPD can lower unplanned downtime, extend motor and drive life, and reduce replacement costs. Its robust warranty simplifies budgeting, while its straightforward installation minimizes commissioning time in new builds or retrofits.
