FAQs
The SPM300400Y1T is a 230/400 V Wye (4W+G) surge protection device designed for use in industrial control panels and machine enclosures. It features a NEMA 4 enclosure with an internal terminal breaker for simple, safe wiring and reliable performance in harsh environments. When planning installation, verify panel clearances and ensure compatibility with your control panel’s bus and wiring scheme to minimize wiring complexity and maximize protection coverage.
A 300 kA per phase rating means the device can absorb high-energy transient events without performance degradation, protecting connected equipment such as drives, contactors, and sensitive electronics. This high rating translates to reduced risk of overvoltage damage during lightning strikes or switching surges, lowering the likelihood of ancillary repairs and downtime in mission-critical systems.
The SPM300400Y1T is RoHS compliant and UL-listed under UL 1449 and UL 1283, with CSA certifications also noted. These certifications confirm electrical safety, performance under surge conditions, and compliance with global regulatory expectations, making it suitable for regulated manufacturing environments and systems that require traceable certification for audits.
Eaton offers a 15-year warranty from the date of delivery, with a 20-year warranty available when the device is registered on Eaton’s SPD portal. This extended coverage supports long-term asset protection and reduces total cost of ownership. Routine maintenance primarily involves visual inspections and monitoring the surge counter to determine replacement timing if surge activity is high.
Ideal for industrial panels, machine control enclosures, and critical process lines, especially where 230/400 V power distribution is standard. Use cases include motor drives, automation cabinets, data centers, and outdoor or damp environments where a robust NEMA 4 rated enclosure and surge counter enhance reliability, monitoring, and compliance in a single, integrated protection device.
