Eaton’s SPD Series (Sidemount Versions) Data Sheet
High surge capability up to 100 kAIC provides robust protection against transient overvoltages, safeguarding sensitive drives and contactors. This reduces unplanned downtime and equipment replacement costs in harsh industrial environments, improving overall equipment effectiveness. The device is ideal for panel boards and motor control centers in manufacturing lines powered by 240V delta systems, ensuring consistent protection where it matters most. The 240V delta (3W+G) input compatibility simplifies protection planning and reduces wiring changes during retrofits, accelerating project timelines and lowering installation risk. It enables faster commissioning and fewer field modifications when upgrading protection strategies across OEM equipment, PLC-controlled machines, and distribution networks. The NEMA 1 enclosure with internal disconnect provides safe indoor protection and simplifies maintenance, enabling quick isolation of the SPD during servicing while reducing arc-flash exposure. External side mounting enables straightforward installation outside main equipment enclosures, supporting retrofit projects and space optimization in crowded electrical rooms. The 15-year warranty and UL 1449 certification deliver long-term reliability and regulatory confidence, lowering lifecycle costs by reducing replacement cycles and warranty-backed support for enterprise facilities, data centers, and heavy manufacturing environments. Compact dimensions and a standard feature package speed up installation, making protection for 320 L-G and 320 L-L operating voltages in 240V delta systems a practical reality for system integrators.
