OEX ACX1864BL 30A Type I Cycling Automatic Reset Circuit Breaker Plated Steel 10-32 Stud Terminals
The OEX ACX1864BL is a Type I cycling automatic reset circuit breaker rated at 30A. It automatically cycles and resets until the overload condition is cleared, providing self-recovering protection for circuits where momentary overloads are expected or where unattended operation is required. Plated steel case with integrated mounting bracket and two 10-32 stud terminals. Mounts via two 5.61mm holes at 39.62mm centre-to-centre spacing. Supplied as a single unit. Covered by a one year warranty.
Product overview
A Type I cycling circuit breaker trips when current exceeds the rated threshold and then automatically resets once the element cools, repeating this cycle until the overload is corrected or removed. This self-recovering behaviour suits circuits with expected momentary overloads electric cooling fans, electric actuators, trailer accessory feeds and marine auxiliary circuits where brief current spikes are normal and self-recovery without operator intervention is desirable. The cycling behaviour also provides a warning signal in some installations, as repeated on/off cycling indicates a persistent overload that needs attention.
At 30A the ACX1864BL covers mid-to-high current accessory circuits, stepping up from the 25A ACX1862BL. The plated steel case and integrated mounting bracket provide durable construction for panel and bracket installation. The 10-32 stud terminals accept standard #10 ring terminals. The two 5.61mm mounting holes at 39.62mm centre-to-centre suit standard panel and bracket mounting configurations.

Frequently asked questions
What is a Type I cycling circuit breaker? A Type I circuit breaker automatically resets by cycling it trips when current exceeds its rating, then automatically resets once the element cools, repeating this cycle until the overload is corrected or removed. This differs from a Type III manual reset breaker, which stays tripped until physically reset by the user.
How does this differ from the manual reset circuit breakers in the OEX range? The ACX1864BL automatically cycles on and off until the fault is cleared without user intervention. The OEX manual reset breakers (ACX1842 through ACX1848) stay tripped until physically reset. Automatic reset suits accessories, fans and auxiliary circuits where brief overloads are expected and self-recovery is desirable. Manual reset is generally preferred for main battery protection where sustained fault re-energisation could cause damage.
What cable terminals suit the 10-32 studs? The 10-32 thread accepts standard #10 ring terminals. Select ring terminals sized for your cable gauge with a #10 (approximately 3.5mm) hole.
