Special features
Standard with surge counter
Feature: The SPM300240S3T provides a 300 kA per phase surge rating in a single-module design. Business Impact: This high-energy capability dramatically reduces the likelihood of damage to downstream equipment during grid transients, extending the life of controllers, drives, and motors. Application: Use in 120/240 V panels where surges are frequent, such as data centers, automation cabinets, and manufacturing lines. Feature: 120/240 V split-phase compatibility. Business Impact: Simplifies wiring and reduces integration risk by aligning with common commercial and industrial power distributions. Application: Streamlines installation in mixed-load environments and retrofit projects where panel configurations vary. Feature: NEMA 4 enclosure with internal terminal breaker. Business Impact: Delivers reliable protection in damp or outdoor spaces while keeping wiring tidy and accessible for service. Application: Outdoor substations, plant entrances, and exposed electrical rooms benefit from robust protection. Feature: Standard surge counter. Business Impact: Enables traceable protection performance and straightforward maintenance planning. Application: Facility audits, preventive maintenance cycles, and compliance reporting are improved with verifiable surge events. Feature: RoHS compliant with multiple certifications (UL 1449, UL 1283, CSA). Business Impact: Supports procurement with confidence and reduces regulatory risk across markets. Application: Ideal for regulated industries and international installations needing certified protection. Feature: 15-year warranty (20 years when registered). Business Impact: Lowers total cost of ownership and provides long-term reliability guarantees. Application: Critical processes and equipment fleets benefit from predictable protection lifecycles.

FAQs
Installation involves mounting the unit in the panel, wiring line and load to the internal terminals, and securing the enclosure per local codes. The SPM300240S3T includes an internal terminal breaker for simplified wiring, and its RoHS-compliant design helps ensure safe integration across industrial environments. Always refer to the Eaton datasheet for exact terminal arrangements and torque specs.
A 300 kA per phase rating indicates the SPD can safely absorb high-energy transient events without degradation. This reduces the risk of downstream component damage, extends life for drives and controllers, and minimizes unplanned outages. For facilities with frequent power quality disturbances, this rating supports robust, long-term protection.
Yes. The device is RoHS compliant and carries certifications including UL 1449, UL 1283, and CSA Electrical Notice NO. 516 Edition 1. These certifications validate safety, performance, and regulatory alignment for diverse markets, helping simplify procurement and compliance processes.
The unit includes a 15-year warranty from delivery, extending to 20 years when registered on Eaton’s SPD site. This long-term warranty lowers total cost of ownership by reducing replacement and service costs, improving ROI for mission-critical applications and facilities with strict uptime requirements.
Ideal for 120/240 V split-phase industrial and commercial panels, including data centers, manufacturing lines, building automation stations, and outdoor electrical rooms. The rugged NEMA 4 enclosure, internal breaker, and surge counter make it suitable for harsh environments and facilities needing reliable protection, easy monitoring, and regulatory compliance.
