OEX ACX2086/5 60A Mini Manual Reset Circuit Breaker Type 3 Switchable Box of 5

A compact, IP66-rated 60A circuit breaker built for automotive, marine, and 4WD electrical systems — pack of 5.

Product Overview

The OEX ACX2086/5 is a pack of five 60A Type 3 mini manual reset circuit breakers designed for surface-mount installation in automotive, 4WD, caravan, and marine electrical systems. Type 3 manual reset means the breaker trips automatically under fault conditions and must be manually reset to restore the circuit — with the added convenience of a switchable function, allowing the circuit to be intentionally opened and closed by the operator when needed.

Rated at 32V DC and housed in UL 94V-0 thermal plastic, each breaker carries an IP66 environmental rating and meets SAE J553, SAE J1171, and UL1500 (ignition protected) compliance standards — making them suitable for fuel-system-adjacent and marine applications where ignition protection is a requirement. Stud insulators are included, and terminal lugs suit 6mm or ¼ inch hardware. At just 58.2mm × 35.7mm × 34.7mm, these are a compact, professional-grade solution for protecting high-current circuits in tight installations.

Features & Benefits

• Type 3 manual reset with switchable function — Trips automatically under overload or short-circuit conditions, requiring a deliberate manual reset rather than auto-resetting unexpectedly. The switchable function also allows the operator to intentionally isolate the circuit — useful for service, maintenance, or staged installations.
• IP66 rated — Fully dust-tight and resistant to powerful water jets, making these breakers suitable for underbonnet, engine bay, bilge, and exterior panel installations where moisture and road spray are unavoidable in Australian conditions.
• SAE J553, J1171 and UL1500 compliant — Meets internationally recognised automotive and marine electrical standards, including ignition protection certification (UL1500) — essential for fuel-system-adjacent installs in boats, caravans, and 4WDs.
• -40°C to +85°C operating range — Handles extreme temperature swings from cold-climate starts through to underbonnet heat in outback Australian conditions without thermal degradation or nuisance tripping.
• UL 94V-0 flame-retardant housing — The thermal plastic housing is self-extinguishing to UL 94V-0 standard, reducing fire propagation risk in the event of a fault condition near the breaker.
• Compact mini form factor (58.2 × 35.7 × 34.7mm) — Surface-mounts into tight spaces on switch panels, firewall installations, and marine electrical boxes without requiring large cutouts or custom enclosures.
• #10-32 threaded studs with 6mm or ¼ inch lug compatibility — Standard stud size compatible with widely available automotive and marine terminal lugs, simplifying wiring without the need for specialised connectors.
• Pack of 5 — Ideal for workshops, fleet installers, and multi-circuit installations where consistent, professional-grade protection is needed across multiple runs. Reduces per-unit cost compared to purchasing individually.
• Protective stud insulators included — Prevents accidental shorting on adjacent metalwork or components without requiring additional insulation hardware.

Frequently Asked Questions

What does Type 3 manual reset mean for this circuit breaker?

Type 3 means the breaker trips automatically under fault conditions and will not restore the circuit until manually reset by the operator. The switchable function also allows intentional circuit isolation for maintenance or staged commissioning — unlike auto-reset (Type 1) breakers which restore current automatically.

Is this breaker suitable for marine and fuel-system installations?

Yes — the ACX2086/5 carries UL1500 ignition-protected certification and meets SAE J1171, making it compliant for use in marine bilge areas and fuel-system-adjacent automotive and caravan applications where ignition protection is a safety requirement.

What amperage options are available in this pack format?

Box-of-5 packs are available in 40A, 50A, and 60A. If you need a different amperage, single-unit options are available across 10A, 15A, 20A, 30A, 40A, 50A, and 60A in the OEX mini circuit breaker range.

What terminal lugs are compatible with these breakers?

The #10-32 threaded studs accept terminal lugs sized for 6mm or ¼ inch hardware, which are widely available standard sizes across automotive, marine, and electrical supply outlets. Protective stud insulators are included in the pack.

Can these breakers be used in both 12V and 24V systems?

Yes — the breakers are rated to 32V DC, making them compatible with both 12V and 24V electrical systems found in passenger vehicles, 4WDs, trucks, caravans, and marine applications.
