Special features
Standard with surge counter
The 120 kA per phase surge rating provides higher protection against high-energy transients, reducing stress on downstream equipment and the risk of cascading faults. In critical panels and motor control centers, this translates to fewer outages and lower repair costs, enabling more reliable production uptime. The 127/220 V Wye (4W+G) configuration ensures straightforward integration with common industrial power systems, cutting engineering time and minimizing wiring errors during installs or retrofits. A NEMA 4 enclosure with an internal terminal breaker delivers weather-resistant protection and simplified field connections, supporting installation in harsh environments and accelerating commissioning. The standard surge counter enables proactive maintenance by recording surge events, allowing scheduled replacements and justifying protection investments with tangible data. RoHS compliance and broad voltage compatibility support global deployments, reducing regulatory hurdles and streamlining cross-site procurement. A long-term warranty—up to 20 years when registered—further reduces lifecycle risk and total cost of ownership, making this solution a strategic choice for protection across multiple facilities.

FAQs
Yes. The SPM120220Y3T is designed for 127/220 V Wye (4W+G) configurations and integrates with standard Eaton panels. Its single-module form factor simplifies installation, reduces wiring complexity, and aligns with common industrial power architectures, enabling a straightforward retrofit or new-build integration without extensive panel redesign.
The device provides 120 kA per phase surge capability, offering robust protection against high-energy transients. This rating translates to better clamping performance, fewer nuisance trips, and reduced risk of downstream equipment damage, especially in facilities with frequent or severe surge events such as heavy motor starts or switching operations.
Industries with high uptime requirements—such as manufacturing, data centers, and process automation—benefit most. The SPM120220Y3T protects electrical panels, motor control centers, and critical feeders from transient surges, helping maintain production continuity, protect sensitive drives, and ensure regulatory-compliant protection in harsh environments.
Verify UL 1283 and UL 1449 certifications, along with CSA testing (Electrical Notice No. 516 and CSA Std. C22.2 No. 8-M1986) and RoHS compliance. These certifications confirm electrical protection performance, safety, and environmental compliance, enabling acceptance in regulated facilities and multi-site deployments.
The built-in surge counter records events, enabling proactive inspection, scheduled maintenance, and data-driven budgeting. This visibility helps justify the protection investment, reduces unexpected downtime, and supports strategic asset management by providing verifiable protection metrics over the system’s life cycle.
