Whole House Surge Protective Device 7409 SPD, 50kA/Phase, 200kA SCCR, NEMA 4x Enclosure, Type 1 & 2 Rated, Pre-Wired 24 Inch Leads

WORKS WITH ANY 120/240V RESIDENTIAL PANEL AND REQUIRED BY NEC 2023
FOR GENERATOR INSTALLS: Compatible with all major panel brands; NEC 2023 mandates an SPD whenever a generator transfer switch is installed, making this a code-compliant addition. 50 KA PER PHASE CAPACITY WITH 200 KA SCCR HANDLES UTILITY AND INDIRECT LIGHTNING SURGES: Thermally protected MOVs absorb high-energy voltage transients before they reach your panel, appliances, HVAC systems, and sensitive electronics. 24-INCH PRE-WIRED 12-GAUGE LEADS CONNECT TO A 20-AMP 2-POLE
BREAKER IN YOUR PANEL: Mounts directly to any standard 1/2-inch panel knockout via nipple mount; the 20A 2-pole breaker is not included and must be supplied by the installing electrician. NEMA 4X ENCLOSURE RATED FOR INDOOR AND OUTDOOR INSTALLATION IN ALL WEATHER: Corrosion-resistant housing operates from -4°F to 122°F and withstands rain, dust, and humidity, giving installers flexibility to mount inside or outside the home. DUAL-RATED TYPE 1 AND TYPE 2 SPD IN A SINGLE COMPACT UNIT: Type 1 mounts line-side for first defense against incoming surges; Type 2 mounts load-side after the main breaker this unit is field-configurable for either application by your licensed electrician. VISUAL LED STATUS INDICATOR CONFIRMS ACTIVE PROTECTION AT A GLANCE: Solid green LED means all MOV protection elements are intact and working; if the LED turns off after a major surge event, the unit has safely sacrificed itself and requires replacement. PROTECTS AGAINST BOTH HIGH-ENERGY EXTERNAL SURGES AND SMALL DAILY INTERNAL TRANSIENTS: Appliances cycling on and off generate repetitive low-level surges that degrade electronics over time; thermally protected MOVs block both types before damage accumulates.
WHAT'S INCLUDED: SPD unit with 24-inch pre-wired L1, L2, and neutral leads (12-gauge), 1/2-inch nipple mount hardware, and owner's manual; 20A 2-pole breaker not included phone, coax, and ethernet surge protection require a separate point-of-use device
