FAQs
The SPM320400Y1Y installs with a two-module chassis and internal terminal block designed for straightforward field wiring in 230/400 V Wye distribution. It fits standard Eaton protection schemes and supports quick retrofits in existing panels while maintaining UL and CSA compliance. Proper bonding, clean bus connections, and correct wire sizing maximize surge protection performance and minimize startup delays during commissioning.
Rated at 320 kA per phase across two modules, the device provides high-energy surge protection for critical loads. It uses a NEMA 4X enclosure with an internal terminal block, enabling reliable outdoor and harsh environments installation while keeping wiring protected from dust, moisture, or corrosion. This combination supports long-term reliability in demanding industrial settings.
Yes. The combination of 320 kA per phase protection, 230/400 V Wye configuration, and RoHS/UL/CSA listings makes it suitable for protective schemes in data centers, manufacturing floors, and automation panels. It guards critical loads against transients, reduces downtime, and supports regulatory compliance, ensuring your power distribution remains resilient for sensitive equipment and heavy machinery alike.
The device carries UL 1449 and UL 1283 listings, plus CSA certification and RoHS compliance. These approvals verify performance under surge conditions, safety in connected equipment, and environmental responsibility. They help meet electrical codes, insurance requirements, and supplier quality expectations, streamlining procurement and installation across facilities with varying regulatory regimes.
The built-in surge counter provides traceable event data for maintenance planning and audits, enabling proactive replacement planning and fewer unscheduled outages. Coupled with a 15-year warranty (20 years with registration) this reduces total cost of ownership, minimizes downtime, and supports asset longevity in critical protection deployments across industrial automation and data centers.
