Eaton surge protective devices for high-energy surges and transient disturbances

Eaton has a comprehensive line of surge protective devices (SPD) to meet your needs. With innovative, reliable surge protection solutions, Eaton helps reduce costly downtime by protecting sensitive electrical and electronic equipment against the damaging effects of transients. Available in all common voltages and configurations, Eaton surge protection solutions are designed and tested in accordance with IEEE and UL standards.
Surge events—short-term transients in voltage threatening critical downstream equipment—happen for many reasons. including internal devices powering on and off (motors, transformers, photocopiers, fluorescent lighting ballasts, light dimmers, variable frequency drives and more) and external events (lightning, grid switching or electrical equipment in adjacent buildings). Installing appropriately rated surge protection at each location throughout your facility provides a layered defense solution— and helps ensure complete protection of critical equipment.

“Thanks to Eaton’s expert service and dedicated support, we can now focus our energy on serving our community rather than addressing equipment failures. We have saved at least $15,000 in repairs since installing the surge protection devices.”

Introducing the Eaton Power Xpert SPD

With advanced monitoring display and communication capabilities for surge protection devices, the Power Xpert SPD can be used to track and record surge events and protection status on your facility’s power system.

Integrated surge protective devices

Eaton’s SPD series integrated surge protection devices and retrofit surge protective device (RSPF) offers the advanced surge protection for integration directly into Eaton electrical assemblies. With our advanced remote monitoring display, communication capabilities and the lowest possible let-through voltage, Integrated SPD series brings superior protection to Eaton panelboards, switchboards, automatic transfer switches, bus plugs, motor control centers and switchgears. Eaton’s retrofit surge protective device (RSPF) provides a reliable, cost-effective, aftermarket solution for surge protection. Designed for easy field-installation, this is built for installation directly into a panelboard or switchboard without any modifications.
