Product Overview

The OEX ACX2080BL is a compact Type 3 mini manual reset circuit breaker delivering professional-grade overcurrent protection and circuit isolation in a space-efficient surface mount form factor purpose-designed for applications where standard full-size circuit breakers would be impractical or unnecessary. At 10 amps, the ACX2080BL is ideally suited to protecting low-to-medium current auxiliary circuits including interior lighting, USB charging systems, small electronic accessories, switch panels, instrumentation, bilge pump controls, and other circuits in automotive, marine, caravan, and 4WD applications where reliable, resettable protection is required without the bulk or cost of a heavy-duty breaker. The compact 58.2 x 35.7 x 34.7mm dimensions allow the ACX2080BL to be installed in electrical panels, junction boxes, switch panels, and tight under-dash or under-bonnet locations where space is at a premium, while the surface mount design simplifies installation without requiring a dedicated housing or enclosure. The switchable Type 3 functionality allows the ACX2080BL to serve a dual role as both overcurrent protection device and manual on/off circuit isolation switch — enabling the operator to deliberately isolate a circuit without requiring a fault event, which is particularly valuable for marine bilge systems, auxiliary lighting circuits, and accessories that require controlled shutdown capability. The SAE J553, J1171, and UL1500 ignition-protected compliance certifications are significant for marine applications, confirming the ACX2080BL meets recognised international standards for use in fuel-vapour environments where ignition risk must be controlled. IP66 housing certification provides reliable protection against powerful water jets and complete dust ingress, making the ACX2080BL suitable for exposed cockpit, deck, and outdoor equipment installations.

Features & Benefits

10A Type 3 Switchable Manual Reset Combines overcurrent circuit protection with deliberate manual isolation capability, providing both safety and operational control over the protected circuit without requiring a separate isolator switch.

Compact Mini Surface Mount Design The 58.2 x 35.7 x 34.7mm form factor fits neatly into electrical panels, switch panels, and confined spaces where standard full-size circuit breakers are too large, simplifying installation in tight locations.

IP66 Waterproof & Dustproof Housing Rated against powerful water jets and complete dust ingress, enabling reliable installation in exposed marine cockpit, deck, outdoor equipment, and under-bonnet panel locations subject to wash-down and environmental exposure.

UL 94VO Rated Thermal Plastic Housing Fire-resistant housing material certified to UL 94VO flammability standard, providing an important additional safety layer in automotive and marine applications where fire risk from electrical faults must be minimised.

SAE J553, J1171 & UL1500 Compliant Meets recognised international automotive and marine electrical standards including ignition protection certification, confirming suitability for use in fuel-vapour environments such as marine engine bays and enclosed bilge areas.

Extended Operating Temperature Range Rated from -40°C to 85°C for reliable performance across extreme cold and heat conditions encountered in alpine, desert, tropical marine, and industrial mobile equipment applications throughout Australia and beyond.

#10-32 Threaded Studs with Protective Insulators Standard threaded studs accept 6mm or ¼ inch terminal lugs for secure, vibration-resistant connections, with included protective stud insulators maintaining terminal safety and preventing accidental contact.

Technical Specs

Compatible With / Goes Well With

The OEX ACX2080BL is compatible with 12V and 24V DC electrical systems up to 32VDC across passenger vehicles, 4WD, caravans, motorhomes, marine vessels, and light industrial mobile equipment.

Also available in 15A, 20A, 30A, 40A, 50A, and 60A single packs for matching protection to specific circuit requirements, with 5-packs available in 40A, 50A, and 60A for multi-circuit panel builds. Pairs well with OEX distribution blocks, OEX switch panels and accessories, OEX wiring harnesses and cable accessories, and OEX terminal connectors and busbars for complete circuit protection and distribution system installations.

Frequently Asked Questions

What is the difference between IP66 and IP67 ratings on OEX circuit breakers?

Both IP66 and IP67 provide complete dust-tight protection, but differ in water resistance. IP66 is rated for protection against powerful water jets from any direction, making it suitable for wash-down, heavy rain, and exposed outdoor installations. IP67 adds protection against temporary submersion up to 1 metre for 30 minutes, making it more appropriate for bilge and submersion-risk locations. For the majority of panel-mount, under-bonnet, and outdoor accessory circuit applications, IP66 provides more than adequate protection — choose IP67 rated breakers such as the OEX ACX1844 for installations where direct submersion is a genuine risk.

What does UL1500 ignition protection compliance mean and why is it important for marine use?

UL1500 is the Underwriters Laboratories standard for ignition protection of marine products — it certifies that the ACX2080BL is designed and tested to not ignite flammable fuel vapours that may be present in marine engine compartments and bilge areas. This compliance is a requirement under many marine safety standards including those referenced by Australian Maritime Safety Authority (AMSA) guidelines, and is an important consideration when installing electrical components in enclosed spaces near fuel tanks, fuel lines, or bilge areas on boats and vessels.

Can I use the ACX2080BL as both a circuit breaker and an on/off switch for my accessory circuit?

Yes. The Type 3 switchable function allows the ACX2080BL to be manually toggled on and off independently of any fault event, eliminating the need for a separate isolation switch on the same circuit. This makes it particularly practical for auxiliary lighting, bilge pumps, USB chargers, and accessory circuits in panels where space is limited and combining protection and switching functions into one device saves both space and wiring complexity.

What terminal lug size do I need for the ACX2080BL's #10-32 threaded studs?

The ACX2080BL's #10-32 threaded studs accept terminal lugs with a 6mm or ¼ inch hole — sometimes described as a #10 or M5 lug in automotive and marine wiring accessories. For a 10A circuit, appropriately sized wire (typically 14 AWG / 2.5mm² for most applications) terminated with a correctly sized ring terminal lug crimped securely onto the conductor is recommended. Always use a ratchet crimping tool for reliable, gas-tight crimps and ensure the lug hole matches the 6mm or ¼ inch stud size for a secure fit.

What other amperage options are available in the OEX ACX2080 Mini Circuit Breaker range?

The ACX2080 series is available in single packs across seven amperage ratings: 10A (ACX2080BL), 15A, 20A, 30A, 40A, 50A, and 60A — allowing you to match the breaker precisely to the current requirements of each individual circuit. For multi-circuit protection panels, 5-packs are also available in 40A, 50A, and 60A ratings. All variants share the same compact Type 3 switchable mini form factor, IP66 rating, and SAE/UL compliance, making it straightforward to standardise on the ACX2080 series across an entire electrical system build.
