Eaton’s SPD Series (Sidemount Versions) Data Sheet
The SPD100400Y2M delivers a 100 kAIC interrupt rating, providing robust surge handling that minimizes the chance of transient events propagating to sensitive equipment. This directly reduces downtime, extends the life of motors, drives, and PLCs, and lowers maintenance costs across production lines. The unit uses a NEMA 1 enclosure with internal disconnect and an external sidemount mounting method, simplifying installation and retrofit work in existing distribution gear while reducing field wiring complexity. Operating at 320 V L-N, 320 V L-G, 320 V N-G and 640 V L-L for 230/400V wye systems, it protects across all common voltage paths, delivering consistent protection where it’s needed most. A 15-year warranty supports long-term budgeting and asset protection, while the standard feature package ensures quick deployment without special orders. Designed for commercial and industrial power distribution, the SPD is compatible with a wide range of accessories and supports straightforward commissioning, even in tight spaces. Overall, this surge protection device enables improved uptime, regulatory confidence, and lower total cost of ownership for modern facilities.

FAQs
The SPD100400Y2M is designed for external sidemount installation with a NEMA 1 enclosure and an internal disconnect. Mounting on the side of distribution equipment reduces the footprint inside panels and enables straightforward wiring with standard conductors, accelerating commissioning while preserving enclosure integrity.
A 100 kAIC rating indicates the device can safely interrupt a surge event up to 100 kiloamps at the point of installation, significantly reducing the risk of damage to breakers, drives, and controllers during high-energy transients common in industrial environments.
Yes. The unit is specified for 230/400V wye (4W+G) configurations and supports protection across L-N, L-G, N-G, and L-L paths, making it suitable for typical industrial power distribution networks.
SPD100400Y2M carries UL 1449 certification and uses a NEMA 1 enclosure with external sidemount mounting, delivering verified safety and reliable indoor protection for general-purpose electrical rooms.
With a 15-year warranty and durable sidemount design, the device reduces downtime, extends asset life, and lowers lifecycle costs. Its compatibility with standard accessories also simplifies retrofits and procurement, improving total cost of ownership.
