BRILLTECH 6 Pack 60AMP 240V Non-Fused AC Disconnect Box
Best for multi-unit outdoor HVAC needs and light commercial use. This metal enclosure features a rugged case, a pull-out switch, and a 240VAC rating at 60A. It is UL listed for safety and designed for weather-resistant outdoor operation. The 1-phase, 3-wire, 2-pole configuration makes it straightforward to wire with standard outdoor circuits. Caution: ensure enclosure mounting and weather sealing align with local code requirements for outdoor installations.
Who it’s best for: contractors and property managers installing several disconnects at an outdoor central HVAC site or multiple outdoor units. Why selected: rugged build, UL listed safety, and 60A capacity support reliable outdoor power isolation.
Z PDBX-60AN 6 Pack AC Disconnect Box 60A 240V
Best for high-volume installations or replacements where multiple outdoor disconnects are needed. This non-fused disconnect provides 60A at 240V with a pull-out switch configuration. Designed for outdoor or exposed environments, it offers straightforward wiring and a compact footprint. Limitation: being a non-fused box, it relies on the upstream breaker for overcurrent protection; ensure proper protection sizing in the panel.

BRILLTECH 1Pack 60AMP 240V AC Disconnect
Best for single outdoor HVAC installations requiring a robust disconnect with weather resistance. The rugged metal case and pull-out switch support safe isolation for 60A loads at 240V. It’s UL listed and designed for outdoor use with Type 3R protection. Caution: verify compatibility with your unit’s nameplate and breaker size to ensure proper protection.
Who it’s best for: homeowners or small contractors installing a standalone outdoor AC. Why selected: compact, durable, UL-listed unit ideal for one-unit setups.
Suplevel 60 Amp Non-Fused Disconnect
Best for outdoor HVAC setups with a need for wide wire gauge accommodation. This NEMA 3R outdoor weatherproof enclosure handles up to 60A and supports circuits from 30A to 50A when upgraded safely. It uses heavy-duty steel with baked enamel finish for corrosion resistance. Caution: wire gauge range is broad but verify compatibility with your circuit’s wire size in practice.
Who it’s best for: projects that may evolve from 30A to 60A circuits, or installations needing strong external protection. Why selected: wide wiring compatibility, durable exterior rating, and practical for evolving systems.
Halex 60 AMP Metallic Non-Fused Disconnect
Best for general outdoor disconnect needs with visible shutoff. The Halex unit offers a 60A rating with a pull-out switch suitable for 120/240V loads. It is a metallic enclosure designed for outdoor use and safety isolation during installation. Caution: confirm that the equipment you’re disconnecting does not require a fused disconnect or separate protection device in the circuit.
Who it’s best for: tradespeople seeking a straightforward, rugged outdoor disconnect for HVAC or similar loads. Why selected: simple, effective, and well-suited for general outdoor disconnect tasks.
Buying Guide
How to choose the right AC disconnect box for outdoor use:
- Load rating: Most listed options are 60A; verify your unit’s nameplate and matching breaker size to avoid over- or under-protection.
- Fused vs non-fused: Non-fused disconnects rely on upstream protection. If you need integrated overcurrent protection, choose a fused model or pair with a properly rated breaker.
- Voltage and phase: Ensure the box supports 120/240V single-phase systems common for residential HVAC and heat pumps.
- Outdoor rating: Look for NEMA 3R or Type 3R ratings, weather-resistant construction, and corrosion-resistant enclosures for exposed installations.
- Wiring compatibility: Check lug sizes and wire gauge support to handle current loads and wiring for 6 AWG to 10 AWG ranges as needed.
- Mounting and accessibility: Consider mounting height, ease of pull-out switch operation, and clear labeling for safe servicing.
Frequently Asked Questions
- What is an AC disconnect box used for?
It provides a clear, accessible point to disconnect power to an outdoor air conditioning unit for service or safety.
- Do I need a fused disconnect for outdoor AC units?
Not always. Non-fused disconnects are common when upstream protection is sized correctly. Fused disconnects offer built-in overcurrent protection.
- What does NEMA 3R mean for outdoor boxes?
NEMA 3R indicates weather resistance against rain, sleet, and dirt, suitable for outdoor use.
- Can I use a 60A disconnect for a 50A circuit?
Yes, a 60A disconnect can be used with a 50A circuit, but ensure the protection device and wiring are appropriately sized for safety and code compliance.
- How many disconnects do I need for multiple outdoor units?
One disconnect per outdoor unit is typical; for multi-unit installations, consider a 6-pack or multi-pack option to streamline wiring and inventory.
