The SPD100240H1Q delivers a 100 kAIC interrupt rating, providing robust surge handling that safeguards critical loads and reduces the risk of cascade failures in power distribution systems. This translates to lower maintenance costs and less downtime when transient events occur. The 240V delta (4W+G) rating aligns with common industrial configurations, ensuring reliable protection across phases while minimizing nuisance tripping and design compromises. Its NEMA 4X stainless steel enclosure and external side mounting offer rugged environmental protection and straightforward retrofit or expansion in outdoor and washdown areas, speeding installation and serviceability. Flexible operating voltages—150 L-N, 150 L-G, 150 N-G, 300 L-L—enable universal protection across mixed circuits, simplifying panel design and reducing part variety. Coupled with a 15-year warranty and UL 1449 certification, the device supports long-term total cost of ownership, compliance, and predictable performance for motor controls, distribution panels, and process equipment. In practice, this means fewer replacement parts, faster fault diagnosis, and consistent protection across changing system demands.

FAQs
The SPD100240H1Q is designed for industrial and commercial power distributions, including outdoor enclosures, control panels, motor control centers, and process lines. Its 100 kAIC rating plus a 240V delta configuration provide reliable protection for sensitive electronics and motor-driven equipment in demanding environments.
When a surge event occurs, the SPD100240H1Q clamps excess voltage to safe levels, absorbing energy up to 100 kAIC. This protects downstream circuitry, reduces insulation stress, and minimizes the likelihood of damaging transients propagating through the system, enabling faster recovery and less downtime after disturbances.
Yes. The unit is housed in a stainless steel NEMA 4X enclosure, offering superior resistance to dust, water, and washdown conditions. The external side mounting design also facilitates installation in exposed or outdoor areas, improving serviceability and reducing enclosure-related retrofit challenges.
External side mounting requires accessible mounting surfaces and proper clearance for wiring, cooling, and maintenance. Use the provided installation instructions to connect L-N, L-G, N-G, and L-L circuits correctly, ensuring compatibility with 240V delta systems. Verify enclosure integrity after mounting and follow UL 1449 guidelines for safe operation.
SPD100240H1Q carries a 15-year warranty and UL 1449 listing, confirming safety and compliance with industry standards. The stainless steel NEMA 4X enclosure further ensures environmental protection, while its rugged construction supports long service life in challenging industrial settings.
