521-SPD60 Surge Protector 60000 Amp

Product Description

The 521-SPD60 is a surge protective device rated at 60,000 amps, designed to guard electrical systems against transient voltage events and power surges. Surge protectors of this class are installed at the service entrance or panel level to divert damaging surge current away from connected equipment. The 521-SPD60 is suited for residential and light commercial electrical installations where equipment protection from lightning strikes and utility switching events is required. Installation is typically performed by a licensed electrician.

The 521-SPD60 is appropriate for service entrance or distribution panel applications in residential and light commercial settings. It provides whole-system surge suppression by clamping transient voltages before they reach downstream loads such as HVAC equipment, motors, controls, and electronics. Consult local electrical codes for required surge protection placement and ratings.
