300 kA per phase surge rating provides strong protection for drives, PLCs, and power supplies from lightning surges and switching transients. The business impact is measurable: fewer nuisance trips, less downtime, and extended life for motor starters and control electronics in manufacturing lines and process equipment. The rugged NEMA 4 enclosure with an internal terminal breaker enables reliable installation in damp, dusty, or outdoor environments without additional enclosure work. This compatibility simplifies mounting on existing panels and reduces field wiring complexity, accelerating project timelines and lowering installation costs. Standard with a surge counter provides event tracking for maintenance planning and warranty validation. This feature supports compliance audits and helps technicians schedule proactive replacements, reducing unplanned downtime and sustaining safety in critical processes. UL 1283 and UL 1449 certifications, CSA notices, and RoHS compliance verify electrical safety and regulatory alignment across North American markets. Procurement teams benefit from a clear specification path and reduced risk during audits, while integrators can demonstrate compliance with customer requirements in OEM builds. With a 15-year warranty from delivery, extending to 20 years when registered on Eaton's site, this SPD aligns with long-term asset management strategies. The combination of solid protection, a built-in counter, and field-proven reliability translates into lower maintenance costs and higher system availability across 24/7 operations.
