Eaton NSB SPD1K0125 Surge Protective Device Module

The Eaton NSB SPD1K0125 Surge Protective Device Module is a dedicated surge protection component identified by part number SPD1K0125. This unit is sold as a single item (EA) and appears in listings alongside Other Load Centers Meters Electrical Enclosures. As a surge protective device module, its primary purpose is to shield electrical equipment from transient voltage spikes that can occur on distribution circuits. Surge protective devices are typically installed in electrical enclosures to intercept transient surges from lightning strikes or switching events, helping to protect downstream equipment and improve system reliability. The SPD1K0125 designation within Eaton's NSB line identifies the exact module used for surge protection in compatible NSB installations. The product listing groups it with Other Load Centers Meters Electrical Enclosures, signaling its role as a modular accessory within those systems. With the SPD1K0125 module, technicians can maintain the protection strategy by replacing a single protective module without reconfiguring the entire enclosure.
