The SPM300600Y3T is a robust surge protection device designed for 347/600 V Wye electrical systems, featuring a Max series single-module format. This combination delivers reliable transient suppression with a documented 300 kA per phase rating, reducing EMI and protecting downstream drives, PLCs, and motors. The enclosure is NEMA 4 rated with an internal terminal breaker, enabling safer wiring and maintenance in harsh environments while streamlining installation. A built-in surge counter provides immediate visibility into event activity, aiding preventive maintenance and reporting. The unit’s RoHS compliance and multiple safety certifications (UL 1449, UL 1283, CSA standards) support regulatory alignment and supply-chain reliability. In practice, this translates to lower maintenance costs, fewer unexpected outages, and easier downstream integration with existing protection schemes in industrial control panels. The design also supports straightforward retrofits in upgrades to aging protection architectures, enabling a measurable improvement in uptime and asset longevity. Compatibility with 347/600 V Wye configurations makes it an ideal fit for data centers, manufacturing cells, and power distribution offices that demand dependable surge protection without extensive panel redesigns, while its weight and dimensions simplify handling and installation in constrained spaces. Long-term durability is reinforced by the warranty framework (15 years standard, 20 years with registration), reducing total cost of ownership for facilities prioritizing reliability in demanding environments.

FAQs
Plan a clean wiring path to the internal terminal breaker and use proper conduit coordination for 347/600 V equipment. The SPM300600Y3T’s NEMA 4 enclosure provides weather resistance, while its single-module footprint reduces panel complexity. Ensure adequate clearance for heat dissipation and easy access for surge counter checks during maintenance.
A 300 kA per phase rating allows the SPD to safely absorb large transient energies without stressing downstream devices, preventing voltage overshoot that could damage motors, drives, and PLCs. This leads to longer equipment life, reduced downtime, and better alignment with industry surge profiles in heavy manufacturing environments.
Yes. The NEMA 4 enclosure provides weather resistance suitable for outdoor panels and washdown environments when installed correctly. The internal terminal breaker simplifies wiring, and the surge counter aids ongoing monitoring. Follow enclosure mounting guidelines and local codes to ensure proper operation in outdoor or harsh settings.
This SPD carries UL 1449 and UL 1283 listings, CSA C22.2 No. 8-M1986, CSA Electrical Notice NO. 516 Edition 1, and RoHS compliance. For regulated facilities, ensure procurement specs reference UL/CSA compliance and RoHS, and verify registration requirements for extended warranty or approvals.
The SPD helps prevent unplanned downtime by protecting critical loads from surges, while the surge counter enables straightforward maintenance logging. The 15-year warranty (20 years with registration) lowers lifecycle costs. By avoiding drive or transformer damage, facilities see reduced replacement parts, improved uptime, and a clearer case for total cost of ownership to stakeholders.
