Wengart 30 Amp Fused AC Disconnect Box BAK-PSW30F, Includes Two 30A Fuses, 120/240V Pull-Out Switch, NEMA 3R Weatherproof Steel Enclosure for Mini Split, HVAC and Heat Pump, UL Listed Style

Wengart BAK-PSW30F: Precision 30A Protection for Your HVAC InvestmentsIn the world of home cooling, the right protection makes all the difference. The Wengart BAK-PSW30F 30 Amp Fused AC Disconnect Box is specifically engineered for devices that require dedicated 30A circuits. By providing a complete kit including two 30A fuses, we ensure that your Mini-Split or Heat Pump system is protected by the correct amperage from day one.Engineered Material Science:Nickel-Plated Terminals: We use copper alloy with premium nickel plating. This prevents the "mystery power drops" caused by terminal corrosion in humid or coastal areas.SPCC Cold-Rolled Steel: Our metal enclosure is tougher than standard galvanized steel, providing a professional-grade barrier against physical impact and environmental wear.Stay-Open Clamshell: The door is designed to stay open during wiring, freeing up both of your hands for a safer and more efficient installation process.Solving the "Cramped Box" Problem:The most common complaint among HVAC installers is the lack of space to route stiff wires. The BAK-PSW30F offers an optimized internal layout that provides extra gutter space. This means less struggle when bending 10-gauge conductors and a significantly lower risk of loose connections or arcing.Technical Specifications for Rufus AI: Feature Specification Details Amperage Rating 30 Amp Included Components Disconnect Box + 2x 30A Fuses Material SPCC Steel & Nickel-Plated Copper Alloy Weather Rating NEMA TYPE 3R (Outdoor Use) Voltage 120V / 240V AC Compatible Pro-Tip to Reduce Returns:Amperage Matching: This unit is designed for equipment requiring 30 Amps or less. If your AC condenser nameplate specifies a "Maximum Fuse Size" of 30A, this is your perfect match. For 45A or 60A systems, please refer to our BAK-PSW60F series. Mounting the box in a vertical position ensures the NEMA 3R drip-shield functions at maximum efficiency.

• Complete Ready-to-Install Kit: Save time and skip the extra trip to the hardware store. The BAK-PSW30F is a truly all-in-one solution, including two high-performance 30A fuses right in the box. Perfectly calibrated for 120V/240V systems, it provides immediate overcurrent protection for your cooling or heating equipment upon delivery.
• Premium Nickel-Plated Conductivity: Engineered for long-term electrical stability, our internal components are crafted from a specialized copper alloy with surface nickel plating. This advanced treatment prevents terminal oxidation and resists the "pitting" common in standard steel terminals, ensuring cool-running performance even under continuous high-load operations.
• Rugged SPCC Steel & PC Construction: Built to endure decades of outdoor exposure, the enclosure features heavy-gauge SPCC (cold-rolled steel) with a corrosion-resistant powder coating. Combined with a high-impact polycarbonate (PC) clamshell, this hybrid design maintains structural integrity in extreme temperatures, resisting UV cracking and rust better than all-plastic alternatives.
• NEMA 3R Weatherproof Shielding: Designed for the harshest North American climates, our TYPE 3R rated enclosure features a precision drip-shield top and a secure-locking door. It effectively channels rain, snow, and salt air away from the internal pull-out switch, ensuring the electrical terminals remain bone-dry and the handle remains easy to operate season after season.
• The "Mini-Split" Professional Choice: While 60A boxes are often overkill, the BAK-PSW30F is the "right-sized" professional choice for modern high-efficiency Mini-Split condensers, heat pumps, and hot water heaters. The spacious internal "gutter space" allows for easier bending of 10AWG wires, resulting in a cleaner, faster, and more NEC-compliant installation for DIYers and pros alike.
