High surge capacity translates directly to equipment longevity and reduced downtime. The SPM400240D3X delivers 400 kA per phase, enabling fast clamping of transient events without interrupting process flows, which is crucial in applications with variable loads such as motor drives and PLC panels. This means fewer unplanned outages and a lower total cost of ownership for industrial power systems. The rugged NEMA 4X enclosure with an internal terminal block offers reliable protection against dust, moisture, and corrosion while simplifying field wiring and maintenance access in harsh environments. A built-in surge counter provides real-time insight into surge activity, enabling proactive maintenance and data-driven asset management. The unit’s RoHS compliance and certifications (UL 1283, UL 1449, CSA) support compliance across industrial facilities and regulatory audits, reducing risk during vendor qualification. Compatibility with 240 Delta (3W+G) systems makes this SPD a drop-in upgrade for modernizing control panels, speed controllers, and automation cabinets while maintaining cabinet footprint and clearance. The included features address common objections about installation complexity and monitoring by offering straightforward wiring, robust protection, and transparent diagnostics that drive measurable uptime improvements.

FAQs
The SPM400240D3X uses an internal terminal block designed for straightforward wiring inside standard control panels. Plan for proper clearance around the NEMA 4X enclosure, secure mounting, and routing of conductors to minimize EMI. Verify voltage rating of 240 Delta (3W+G) and ensure the unit is mounted in a damp-free environment as per the enclosure requirements.
A 400 kA per phase rating indicates the maximum surge current the SPD can safely divert without compromising performance. This high rating is important for protecting drives, PLCs, and sensors in demanding industrial applications where large transient events can occur, reducing the risk of insulation damage and data loss.
Yes. The device is RoHS compliant and UL listed (UL 1283 and UL 1449) with CSA certifications, ensuring compliance with safety and environmental standards across North American installations and aiding regulatory audits.
The surge counter provides visibility into surge activity for maintenance planning and performance trending, while the NEMA 4X enclosure offers weatherproof and corrosion-resistant protection suitable for harsh environments, enabling reliable installation in outdoor or damp panel locations.
The SPD carries a 15-year warranty from delivery, with a 20-year option when registered on Eaton’s SPD portal. This extended coverage supports long-term asset protection and reduces lifecycle cost concerns for mission-critical automation systems.
