SURAIELEC 60 Amp Fused AC Disconnect Box
UL Listed and reliable, this 60A, 240V fused AC disconnect is designed for safe power shutoff. It uses a 2-pole, 3-wire, 1-phase configuration to support mini split and light commercial HVAC systems. The weatherproof, rust-resistant galvanised steel enclosure carries a NEMA 3R rating, making it suitable for outdoor use. Its pull-out switch provides a clear ON/OFF indication, and the handle stores inside the unit when OFF to prevent loss. This model is ideal when a fused disconnect is required for outdoor mini split installations.
Suplevel 30 Amp Fused AC Disconnect Box
This NEMA 3R weatherproof enclosure uses a 30A, 240V fused disconnect with a pull-out switch. It accommodates a range of wiring configurations with pre-drilled holes, side/bottom/back knockouts, and a three-piece design to simplify mounting and wiring near outdoor AC units. The enclosure resists rain, dust, and corrosion, ensuring durability in sun, wind, and storms. A linked protective shield cuts power when the handle is removed, and a lockable cover provides additional security against tampering.

The enclosure provides weather resistance and straightforward wiring to ensure a safe and compliant disconnect point for outdoor systems.
Buying Guide: Key Purchase Considerations
When selecting a mini split disconnect box, consider the following factors to match your installation needs:
- Current rating: Choose according to your system’s amperage requirements (30A versus 60A). Overrating is acceptable but unnecessary cost can be avoided.
- Voltage and wiring: Ensure compatibility with 240V single-phase systems and the 2-pole, 3-wire configuration. Check if the fuse is included or needs to be purchased separately.
- Enclosure rating: For outdoor use, select a NEMA 3R or equivalent weatherproof enclosure to resist rain, dust, and corrosion.
- Protection type: Fused versus non-fused disconnects affect protection and service procedures. Fused units provide short-circuit protection; non-fused units require separate overcurrent protection upstream.
- Safety features: Look for visible ON/OFF operators, lockable covers, and anti-misoperation designs to prevent accidental disconnection or tampering.
- Durability and material: Galvanized steel enclosures offer robust outdoor performance—consider rust resistance, heat dissipation, and mounting options (wall or fence mounting).
- Installation ease: Pre-drilled holes, knockouts, and split designs can reduce installation time and simplify wiring in tight outdoor spaces.
- Brand and compliance: UL listing and reputation for HVAC safety products help ensure long-term reliability and code compliance.
By weighing these factors, you can select a disconnect box that provides a safe, accessible disconnect point for your mini split or outdoor HVAC equipment while withstanding harsh outdoor conditions.
