Protect your equipment with Eaton surge devices to shunt high energy surges and other transient disturbances through advanced metal oxide varistor (MOV) technology. For over three decades, Eaton has offered solutions coming in all common voltages and configurations, in surge current capacity ratings up to 800 kA and with a variety of optional features. They are independently tested and backed by the largest engineering and technical support team in the industry. In addition, they are tested to meet the latest UL and other agency standards, and many have a nominal discharge current of 20 kA, the highest achievable rating for this parameter indicating device robustness.
Watch this video to learn more about the two main types of panelboard-mounted surge protection devices (SPDs) and why they're crucial for safeguarding sensitive electronic equipment from voltage surges and spikes.
“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.”
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.
Applications: commercial and industrial
Product series |
kA rating | Enclosure | Nominal voltage | Current rating |
| 50-400 kA | NEMA 1, 4, and 4x | 120-600 Vac | Up to 4000 A | |
| Retrofit surge protector (RSPF) | 50 (on units with filtering), 100 | Type 1 enclosure, IP40 | 208-600 Vac | Up to 2000 A |
Eaton side mount versions of surge protective devices are the latest and most advanced UL 1449 5th Edition certified surge protectors. Application of our external mount SPD series, SPC series, CVX series and SP1 series units throughout a facility will ensure that equipment is protected with the safest and most reliable surge protective devices available. Units are available in all common voltages and configurations, and also in a variety of surge current capacity ratings. Available in NEMA 1, NEMA 4 or NEMA 4X enclosures, there is a solution for all electrical applications, including service entrances, distribution switchboards, panelboards and point-of-use equipment.
Applications: commercial/industrial, light commercial, OEM (original equipment manufacturer)
