Standard with surge counter
The two-module design delivers 320 kA per phase protection for 120/240 V systems, providing headroom for multiple transient events without triggering device replacement. By handling high-energy surges, it reduces conductor heating, component wear, and downtime across critical feeders. A rugged NEMA 4X enclosure with an internal terminal block supports outdoor and damp environments while simplifying wiring and field maintenance for faster installations. The standard surge counter enables real-time monitoring of surge activity, aiding preventive maintenance and regulatory reporting. RoHS compliance and certifications (UL 1449, UL 1283, CSA) support safe, compliant deployment in regulated facilities. A 15-year warranty, extendable to 20 years with registration, lowers total cost of ownership and improves long-term budgeting. With dimensions of 9.3 in Ă— 17.5 in Ă— 14.91 in and a 50 lb weight, installation planning and panel fit are straightforward for new builds and retrofits.

FAQs
Yes. The SPM320240S1Y is designed specifically for 120/240 V split-phase systems, using a two-module configuration to deliver high-energy surge protection across both legs of the supply. It integrates with standard Eaton SPD MAX deployments, ensuring straightforward replacement or expansion in existing panels.
The unit provides up to 320 kA per phase of surge protection, enabling it to absorb multiple transient events without activating early or prematurely exhausting protection. This capability helps keep critical equipment like motors, drives, and controllers online during power disturbances, reducing downtime and maintenance costs.
The NEMA 4X enclosure offers rugged protection in damp, dusty, or outdoor environments, while the internal terminal block simplifies wiring, minimizes field connections, and enhances safety during installation and servicing. This design speeds up commissioning and reduces the chance of wiring errors in challenging environments.
The device carries UL 1449 and UL 1283 listings, CSA certifications, and RoHS compliance, reflecting adherence to recognized safety and environmental standards. It is warranted for 15 years from delivery, with a 20-year warranty available upon registration, supporting long-term protection and value.
The surge counter provides continuous visibility into surge events, enabling proactive maintenance planning, trend analysis, and documentation for compliance audits. This feature helps verify ongoing protection effectiveness and informs decisions on panel upgrades or retrofits when surge activity increases.
