FAQs
Installation follows Eaton’s SPD Series mounting guidelines for sidemount configurations. Ensure clearance for access to terminals, maintain ventilation, and secure the enclosure to a stable surface. Connect L-N, L-G, and N-G to the corresponding terminals, and use the basic feature package as specified. Verify proper torque on all connections and perform a functional test after mounting to confirm surge protection functionality.
SPDs for 240V delta (4W+G) systems accommodate high-leg delta configurations, providing clamp protection across L-N, L-G, N-G, and L-L paths. Use this device on motor feeders, pumps, and control circuits where transient events are common. Its 100 kAIC rating ensures robust interruption performance for high-energy surges typical in industrial facilities.
Yes. UL 1449 certification confirms compliance with essential surge suppression safety standards, while a NEMA 4X enclosure offers corrosion resistance and weatherproof protection for indoor and harsh environments. These credentials simplify regulatory approvals, support outdoor installations, and align with project safety and reliability targets.
The device delivers a 100 kAIC interrupt rating, indicating strong transient handling capacity. Its operating voltages cover 150 L-N, 150 L-G, 150 N-G, and 300 L-L across a 240V delta system. By limiting overvoltage exposure to downstream equipment, it reduces component wear, extends drive life, and lowers unplanned downtime.
Expect improved equipment reliability, reduced maintenance costs, and measurable uptime gains. The 15-year warranty supports long-term cost of ownership, while UL 1449 certification and NEMA 4X protection help meet compliance and safety goals. Compatible with sidemount configurations, it simplifies installation alongside existing electrical distribution equipment.
