Eaton SPM120400Y1T SPD MAX surge protector - 120 kA
Part Number: SPM120400Y1T
Quick Summary
Eaton SPD MAX SPM120400Y1T is a surge protection device designed for electrical panels in industrial automation applications. Unmanaged transients drive equipment failures, downtime, and costly warranty claims. This model carries UL 1449 and UL 1283 safety approvals, CSA Electrical Notice NO. 516, and RoHS compliance, with a rugged NEMA 4 enclosure for harsh environments. Its 120 kA per phase protection and 230/400 V Wye configuration help engineers meet design specs while simplifying procurement. The compact, single-module design supports easy installation in control panels, while the warranty—15 years from delivery (20 years with registration)—contributes to lower lifecycle costs.

Special features
Basic
120 kA per phase surge protection delivers robust transient suppression, reducing the risk of damage to drives, PLCs, and sensors. This translates to lower unplanned downtime and fewer chassis replacements during storm events or switching surges. In industrial automation panels, that means more consistent uptime and predictable maintenance budgets. 230/400 V Wye (4W+G) configuration provides compatibility with common industrial controls, which reduces wiring complexity and speeds up panel commissioning. For process lines and packaging equipment, this means faster turnarounds and simpler scoping of procurement. NEMA 4 enclosure with internal terminal breaker protects the module from moisture, dust, and corrosion, enabling indoor and outdoor placements in harsh facilities. That containment minimizes external cabinet requirements and supports rugged manufacturing floors. RoHS compliance and safety certifications—UL 1449, UL 1283, CSA—align with stringent regulatory standards, expediting approvals and audits. These features reduce total cost of ownership while supporting long-term reliability. The 15-year warranty from delivery (20 years with registration) adds asset protection and predictable budgeting for capital projects. A compact, single-module design also streamlines installation, minimizes panel footprint, and simplifies future upgrades within the Eaton SPD MAX family.

FAQs
The SPM120400Y1T is a single-module SPD designed for 230/400 V Wye (4W+G) systems. Mount in the protected panel, connect Line terminals to L1, L2, L3 and Ground to G, and ensure proper clearance per enclosure guidelines. The internal terminal breaker simplifies wiring while preserving panel space. This configuration minimizes wiring errors and speeds up commissioning in industrial control panels.
This device carries UL 1449 and UL 1283 safety approvals, CSA Electrical Notice NO. 516, and RoHS compliance. These certifications indicate compliance with essential safety and environmental standards, supporting regulatory approvals, factory inspections, and audit readiness. They are particularly important for automotive, food & beverage, and regulated manufacturing environments where strict safety and material restrictions apply.
The SPM120400Y1T includes a 15-year warranty from the date of delivery, with an extended term of 20 years available when registered on Eaton’s SPD site. This extended coverage reduces long-term ownership risk, improves asset lifecycle planning, and supports total cost of ownership considerations for critical protection in automation systems.
Yes. The device is housed in a NEMA 4 enclosure with an internal terminal breaker, designed to withstand moisture, dust, and corrosion. This makes it suitable for outdoor or damp environments commonly found in manufacturing floors, outdoor panels, and harsh production settings, while maintaining reliable surge protection performance.
By limiting transient overvoltage to 120 kA per phase and providing reliable 230/400 V Wye protection, the device reduces unexpected downtime, extends the life of drives and control electronics, and lowers maintenance costs. The combination of RoHS compliance, robust certifications, and a long warranty further lowers lifecycle risk, delivering a favorable return on investment for critical automation assets.
