Eaton SPD100240H2O Surge Protection Device - UL 1449
Part Number: SPD100240H2O
Quick Summary
Eaton SPD series surge protection device guards sensitive electrical gear in industrial and commercial power systems, delivering reliable transient protection where it matters most. Operators and engineers often struggle with unexpected surges, costly downtime, and limited space for protection hardware; this model addresses those frustrations with a compact, install-ready solution. UL 1449 listing and a rugged NEMA 4X enclosure provide certified protection and weather resistance, while the 240V delta (4W+G) design matches common industrial feeders. An external sidemount option, broad operating voltages, and a standard feature package streamline deployment, reduce installation risk, and support compliant, long-term asset protection. The result is improved uptime, safer operation, and predictable lifecycle costs across demanding environments.

FAQs
The SPD100240H2O supports external sidemount installation, designed to simplify wiring and service access in protection schemes. With its compact footprint (9.5 in long, 5.4 in wide, 3.45 in high) and a 3.5 lb weight, it fits into space-constrained panels and enables rapid replacement without removing adjacent gear, reducing downtime during maintenance or upgrades.
This device provides a 100 kAIC interrupt rating, suitable for 240V delta (4W+G) systems. It clamps transient voltages across L-N, L-G, N-G, and L-L paths, protecting downstream drives, motors, and controls. The result is safer operation, fewer nuisance trips, and lower repair costs after surge events.
Yes. The SPD100240H2O uses a rugged NEMA 4X enclosure, delivering weather and dust resistance for outdoor or harsh-indoor environments. Combined with UL 1449 listing, it provides certified surge protection in exposed locations while maintaining reliable performance and safe access for installation and servicing via external side mounting.
SPD100240H2O is UL 1449 listed, validating its surge protection performance and safety. It incorporates a NEMA 4X enclosure to support harsh environments and outdoor installations, and it carries a 15-year warranty, underscoring Eaton's commitment to long-term asset protection and reliability.
The 15-year warranty, reduced downtime, and protection of critical loads translate into a favorable total cost of ownership. By preventing surge damage to drives, controllers, and motors, maintenance intervals can be extended and uptime improved, yielding measurable ROI through fewer unscheduled outages and lower replacement costs for expensive electrical equipment.
