Type 1 Surge Protective Devices

Type 1 Surge Protective Devices are typically mounted on the line side of the main service entrance (between the utility pole and where your electricity enters your service panel). They protect against external surges caused by lightning or utility capacitor bank switching.

Leviton Type 1 SPDs offer first line defense in a whole house surge protection network. These devices are outdoor rated and some of our Type 1 SPDs feature an audible alarm warning that the device is no longer providing the rated surge protection.
