FAQs
Install the SPM300400Y1R in a standard electrical panel sized for 230/400 V Wye systems. Verify adequate clearance for heat dissipation and ensure proper grounding. Wire per local codes, observing the 4W+G configuration, and connect to the internal circuit breaker as required. Use the surge counter for ongoing evaluation and plan routine maintenance around peak surge periods.
The 300 kA per phase rating indicates the SPD can absorb very high-energy surges without failing, preserving expensive drives, motors, and PLCs. In practice this means fewer replacements and less downtime during storms or switching transients, especially on production lines with variable loads. Pairing with RoHS and UL/CSA certifications provides regulatory assurance.
Yes. The unit is housed in a NEMA 4 enclosure with an internal circuit breaker, designed for harsh industrial environments, including damp or dusty areas. It resists moisture ingress and cleanup while maintaining surge protection performance. For outdoor installations, ensure appropriate cable routing and weather protection per local codes, and verify panel ratings remain within the 230/400 V Wye range.
The SPM300400Y1R carries UL 1449 and UL 1283 certifications and CSA standards, with RoHS compliance, aligning with common regulatory requirements in North American facilities. These marks support safe operation, traceability, and warranty eligibility. When evaluating procurements, confirm the product page and datasheet (or specification sheet) reflect the latest revisions to meet evolving compliance needs.
Total cost of ownership is influenced by the long warranty and low maintenance needs. The SPD MAX is covered by a 15-year warranty from delivery, extending to 20 years when registered on Eaton's site, reducing replacement risk over the product lifecycle. The built-in surge counter and durable NEMA 4 enclosure help minimize service calls, downtime, and inventory costs for mission-critical plant equipment.
