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

Descripción

The Generac 7409 is a whole-house surge protective device rated at 50 kA per phase that installs directly at your electrical panel to block damaging voltage transients from utility switching, indirect lightning surges, and appliance-generated internal surges — before they reach your home's electronics, HVAC system, and appliances. Is this a Type 1 or Type 2 device? Both — the 7409 is dual-rated and field-configurable as either a Type 1 (line-side, ahead of the main breaker) or Type 2 (load-side, after the main breaker) SPD, giving your electrician the installation flexibility that best suits your service configuration. What does 50 kA per phase mean? It represents the maximum surge current the device can safely absorb in a single event before its MOV protection elements are consumed. The 200 kA SCCR confirms safe operation in high-fault residential electrical services. Does it protect against direct lightning strikes? No SPD protects against a direct strike to the structure — this device diverts indirect lightning surges that travel through utility distribution lines into your home. Direct strike protection requires a separate lightning rod or grounding system. Does it work with any panel brand? Yes — compatible with any residential single split-phase 120/240V panel, regardless of brand. A 20A 2-pole breaker (not included) is required at installation. How do I know if it needs replacement? The LED indicator is solid green when all protection elements are active. If the LED turns off, the unit has safely reached end-of-life and must be replaced. There is no audible alarm. Does it protect phone or internet lines? No — the 7409 protects electrical circuits only. Coaxial, phone, and Ethernet surge protection requires a separate point-of-use device. Does it work with my home generator? Yes — and per NEC 2023, an SPD is now required whenever a generator transfer switch is installed. Professional installation by a licensed electrician is required for all Type 1 and Type 2 SPD applications. Warranty: 2-year limited on this standalone unit.

Características

• 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
