The SPM250240S3T uses a high-energy surge protection approach rated at 250 kA per phase, providing robust mitigation for critical loads and reducing equipment wear; this translates to fewer fault-induced outages and longer service life for downstream devices. In practical terms, installation on a 120/240 V split-phase system supports common industrial mains while enabling reliable protection for feeders, transformers, and motors in manufacturing lines. The NEMA 4 enclosure with internal terminal breaker delivers weather-resistant performance and safe, code-compliant wiring in both indoor and outdoor environments, minimizing field retrofits and rework. A standard surge counter adds visibility for maintenance teams and utility reporting, supporting proactive replacement planning and compliance documentation. RoHS compliance simplifies disposal and supports environmentally responsible procurement, while UL 1449, UL 1283, and CSA certifications confirm regulatory alignment for critical projects. This unit’s compact single-module design eases integration into existing panels and supports easy installation and serviceability in tight spaces, reducing overall project risk and downtime.

FAQs
Yes. The SPM250240S3T is a single-module surge protection device designed for 120/240 V split-phase systems and uses an enclosure rated for NEMA 4 environments. Its compact dimensions (9.3 in length, 14.91 in width, 17.5 in height) and internal terminal breaker simplify mounting in existing panels without requiring major rewiring.
The unit provides up to 250 kA per phase protection at a 120/240 V split-phase rating. This level of protection mitigates high-energy transients from lightning and switching surges, helping to preserve downstream equipment like PLCs, drives, and control electronics while maintaining uninterrupted operation where possible.
Ideal for data centers, manufacturing floors, and process control environments that require reliable surge mitigation on 120/240 V panel feeds. Its NEMA 4 enclosure suits indoor and some outdoor installations, and its surge-counter feature supports ongoing maintenance and fault-trend analysis in production environments.
The protector complies with UL 1449 and UL 1283 standards and CSA Electrical Notice No. 516 Edition 1, along with CSA Std. C22.2 No. 8-M1986. It also carries RoHS compliance, ensuring regulatory alignment for controlled environments and safer end-of-life handling.
The built-in surge counter enables proactive maintenance planning by signaling when protection performance nears its end of life. The device carries a 15-year warranty from delivery (20 years when registered with Eaton’s SPD portal), reducing replacement risk and downtime while improving long-term ROI through fewer outages and predictably managed maintenance.
