Eaton’s SPD Series (Sidemount Versions) Data Sheet
External sidemount design reduces space conflicts and simplifies installation, enabling quick deployment alongside external distribution equipment. The business impact is faster commissioning and lower installation labor costs for panel builders. This is particularly applicable for 120/208V wye systems in commercial and light industrial environments. The SPD100208Y3L provides a 100 kAIC interrupt rating, delivering robust protection against transient events and minimizing equipment damage, downtime, and costly repairs for motors, drives, and controls. With a NEMA 1 indoor enclosure and operating voltages of 150 L-N, 150 L-G, 150 N-G, and 300 L-L, it integrates smoothly into existing protection schemes with minimal enclosure modification. A standard feature package and surge counter deliver traceability for maintenance planning and compliance reporting, while the 15-year warranty offers long-term value and predictable performance in harsh environments.

FAQs
The SPD100208Y3L is designed for external sidemount installation beside distribution equipment. Connect to a 120/208V wye (4W+G) supply, mount in a compliant indoor location with a NEMA 1 enclosure, and secure via the external mounting method. This approach minimizes panel openings and simplifies retrofits, reducing commissioning time and preserving existing wiring layouts while meeting UL 1449 safety standards.
A 100 kAIC interrupt rating indicates the device can safely interrupt transient surge currents up to 100 kiloamperes at the point of protection without damage. For 120/208V systems, this level of protection helps shield downstream equipment like drives and controllers from high-energy transients, reducing the risk of insulation damage and unplanned downtime during lightning or switching events.
Yes. The SPD100208Y3L is specified for 120/208V wye (4W+G) configurations, supporting three-phase systems with a ground. Its external sidemount design and NEMA 1 enclosure are well-suited for indoor distribution panels and control cabinets in commercial and light industrial environments, delivering reliable protection without requiring a panel retrofit.
The SPD100208Y3L is UL 1449 listed, reflecting compliance with safety and performance standards for surge protection devices. Compliance with UL 1449 helps support installation in regulated facilities and provides assurance to inspectors and procurement teams that the device meets recognized safety criteria for transient protection in indoor electrical distributions.
This SPD includes a surge counter for post-event analysis and traceability, supporting maintenance planning and trend analysis. Coupled with a 15-year warranty, this reduces lifecycle costs by minimizing unexpected replacement cycles, enabling proactive protection budgeting, and delivering predictable downtime reduction in critical manufacturing or facility operations.
