Whole Home Surge Protective Device with Two 15A Breakers — New Open Box
Type 1 SPD | 120V | 25kA Max Surge | 10kA SCCR | Two 15A Thermal-Magnetic Breakers | Plug-On | UL 1449 & UL 489
Genuine Leviton LSPD1-T — a whole home surge protective device and two 15A standard thermal-magnetic branch circuit breakers combined in one plug-on unit for Leviton Load Centers.
You get Type 1 surge protection right at the panel without giving up breaker space: the device protects the whole home and still feeds two 15A branch circuits. Because the surge module is powered from the line side, protection continues even if the breakers are off or tripped. LED indicators show protection status at a glance.
This unit is brand new and never installed — no original box. You receive the exact item shown in the photos.
Model: Leviton LSPD1-T
The "-T" version uses standard thermal-magnetic breakers. (The LSPD1 without "-T" uses hydraulic-magnetic breakers.)

Most surges don't come from lightning — they come from the utility grid and from large appliances cycling on and off inside the home. Over time these small surges wear down the electronics in TVs, computers, appliances, HVAC controls and EV chargers. A Type 1 SPD installed at the panel clamps these surges before they reach your circuits. Since the 2020 NEC (Section 230.67), surge protection is required for new and replaced dwelling unit services.
