Product Overview

The OEX ACX2086BL is the highest-rated variant in the compact ACX2080 mini circuit breaker series, delivering professional-grade 60-amp overcurrent protection and circuit isolation at the maximum capacity of the range in the same space-efficient surface mount form factor shared across all ACX2080 models. At 60 amps, the ACX2086BL reaches the upper limit of what a compact surface mount mini breaker can handle, making it the go-to choice for protecting main auxiliary battery feed circuits, high-output solar system main distribution feeds, large capacity dual-battery interconnects, high-draw inverter input circuits up to approximately 720W (12V) or 1440W (24V), heavy marine thruster main feeds, and multi-output panel primary supply circuits in automotive, marine, caravan, and 4WD installations where the full 60A capacity of the compact ACX2080 form factor is required. The 58.2 x 35.7 x 34.7mm compact dimensions allow installation in electrical panels, switch panels, and confined locations where full-size heavy duty breakers would be impractical, while the surface mount design eliminates the need for a dedicated housing or enclosure. The switchable Type 3 functionality provides dual capability as both overcurrent protection and manual on/off circuit isolation, enabling deliberate circuit shutdown without requiring a fault event — essential for primary battery feed circuits and main system supply lines where controlled isolation is a key safety and operational requirement. Available as both a single pack and a 5-pack, the ACX2086BL is equally suited to single circuit protection and larger multi-circuit panel builds requiring maximum-rated compact protection across multiple outputs. SAE J553, J1171, and UL1500 ignition-protected compliance certifications confirm the ACX2086BL meets recognised international standards for use in fuel-vapour environments on marine vessels.

Frequently Asked Questions

When should I choose the 60A ACX2086BL over the 50A ACX2085BL for my circuit?

Choose the 60A ACX2086BL when your circuit's continuous current draw exceeds 50 amps or when protecting very high-current loads such as main auxiliary battery feed circuits, primary solar system distribution feeds, large capacity dual-battery interconnects, or combined multi-accessory panel feeds where total continuous draw approaches 48 amps. Applying the standard 125% sizing rule, the 60A ACX2086BL is the correct choice for circuits with a maximum continuous draw of up to 48 amps. The ACX2086BL represents the maximum capacity of the compact ACX2080 mini series — for circuits exceeding 48 amps continuous or applications requiring 72VDC voltage tolerance or IP67 submersion protection, the heavy duty OEX ACX1844 is the appropriate step up.

How does the 60A ACX2086BL mini breaker compare to the heavy duty OEX ACX1844 60A breaker?

Both breakers are rated at 60A but are designed for different installation scenarios. The ACX2086BL is a compact surface mount mini breaker suited to panel-mount applications in confined spaces, rated to 32VDC with IP66 protection and SAE/UL1500 ignition-protected compliance for marine environments. The OEX ACX1844 is a full-size Type III heavy duty breaker rated to 72VDC with IP67 submersion-rated protection and larger 9.5mm stainless steel studs for heavier cable gauges. Choose the ACX2086BL for compact panel-mount installations on 12V or 24V systems; choose the ACX1844 when the installation requires 48V system compatibility, submersion-rated IP67 protection, or heavier cable terminations in exposed bilge, deck, or under-bonnet locations.

What terminal lug and cable size should I use for the ACX2086BL on a 60A circuit?

The ACX2086BL's #10-32 threaded studs accept terminal lugs with a 6mm or ¼ inch hole. For a 60A circuit, appropriately sized wire — typically 4 AWG / 16mm² for runs up to 3 metres, or 2 AWG / 25mm² for longer runs or installations where minimising voltage drop is critical — terminated with a correctly crimped ring terminal lug is recommended. Always use a ratchet crimping tool for reliable, gas-tight crimps and confirm the lug hole matches the 6mm or ¼ inch stud size for a secure, vibration-resistant termination.

What does the UL1500 ignition protection compliance mean for marine installations?

UL1500 is the Underwriters Laboratories standard for ignition protection of marine products. It certifies that the ACX2086BL 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.

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

The ACX2080 series covers seven amperage ratings in single packs: 10A (ACX2080BL), 15A (ACX2081BL), 20A (ACX2082BL), 30A (ACX2083BL), 40A (ACX2084BL), 50A (ACX2085BL), and 60A (ACX2086BL), allowing precise matching of breaker rating to each circuit's requirements. The ACX2086BL is also available as a 5-pack for multi-circuit panel builds and fleet installations — as are the 40A and 50A variants. 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.
