Feature: 50 kAIC surge rating provides a generous protection margin for medium-to-heavy surge environments. Business Impact: Reduces the risk of nuisance trips and downstream equipment damage, leading to less unplanned downtime in panels housing motors and drives. Application: Ideal for industrial panels and control gear where transient events are common, helping maintain continuous production. Feature: 347/600V Wye (4W+G) voltage rating with L-N 420 V and L-G 840 V protection levels. Business Impact: Delivers calibrated protection for standard industrial power distribution, aligning with typical plant networks and safeguarding sensors and actuators. Application: Suitable for three-phase systems across manufacturing lines, process controls, and automation cabinets. Feature: Compact form factor and panel-friendly footprint (2.5 in depth, 4.8 in height, 2.9 in width; 1.25 lb). Business Impact: Simplifies installation in crowded panels and reduces mounting time, lowering labor costs. Application: Practical for retrofit projects and new panel builds where space is limited. Feature: UL 1449 certification and 2-year warranty. Business Impact: Provides regulatory assurance and predictable maintenance budgets, supporting compliance programs and supplier reliability. Application: Relevant across facilities seeking documented protection standards for safety and asset longevity. Feature: IP-addressable protection for L-N and L-G in a three-phase configuration. Business Impact: Ensures balanced protection across all lines, improving reliability for PLCs, drives, and instrumentation. Application: Critical for automated lines, packaging equipment, and process control systems.

FAQs
The SP1-600Y is designed for three-phase, four-wire (4W+G) systems. Install according to Eaton's specification sheet, ensuring proper L-N and L-G connections to protect downstream loads such as drives and PLCs. Verify correct voltage rating of 347/600V Wye and compliance with UL 1449 guidance during setup and commissioning.
SP1-600Y offers a 50 kAIC surge current rating, providing ample protection against transient overvoltages from lightning and switching events. This rating reduces the likelihood of downstream equipment damage, supports uptime in moderate-to-heavy surge environments, and aligns with common industrial protection needs for panels housing motors and controls.
Yes. SP1-600Y is explicitly specified as 347/600V Wye (4W+G) and is intended for three-phase installations. This makes it a good fit for industrial facilities with such distribution voltages, protecting downstream equipment like drives, sensors, and controllers from transient overvoltages.
Applications include protection of control panels, motor drives, PLCs, and instrumentation in manufacturing and processing environments. Its three-phase design, high surge rating, and compact form factor support retrofit projects and new panels alike, delivering improved uptime, reduced maintenance needs, and enhanced compliance with safety standards.
SP1-600Y carries UL 1449 certification and includes a two-year warranty, offering regulatory reassurance and predictable support. This combination helps facilities manage risk, plan maintenance budgets, and ensure ongoing protection for critical automation assets in industrial environments.
