RKURCK 9 Amps Thermal Circuit Breakers 125/250VAC 32VDC Automatic Reset Relay Fuse Current Overload Protector Switch 9A 2 Pack

Nice replacement

Woke up my kids power semi. Having the extra headway on amps made a big difference. Wife weighs 125 and it pulls with him in the trailer and her driving. Very good upgrade/replacement.

Replaced 10-amp slow blow fuse with thermal breaker. Thus far breaker has not tripped, unlike fuse. Should breaker trip, at least it will self-reset. Instead of requiring a tear-apart and reassemble.

great small breakers

Got a non functional hikkido jeep, this is all it needed to get up and running!

Given the choice between using single use fast-blow fuses and resettable circuit breakers, the breakers win by a mile! I like that these come in several low amperage models, which are nice for lower current DC projects like ham radios and electronics. Simply based on their shape some might confuse these for ATC fuses. I've included a photo of the micro and standard sized ATC fuses alongside this model of breaker. Sitting on the opposite side is another variation of a resettable breaker from a different manufacturer. As you can see, this one is item is much smaller while still maintaining the same "footprint" for electrical connections. If you're looking to replace an existing breaker, like the larger sized one shown in the photo, this breaker would be a good choice. I have clearly marked this model in the comparison photo. Also on the topic of connections, this breaker has holes in the metal leads to support wire/solder connections. While this breaker may be physically smaller than others, doesn't have any mounting holes or screw threads, and therefore can't be panel mounted. I also noticed this breaker has designated "line" and "load" sides stamped into the plastic housing, making them polarized. The leads are offset from the centerline of the plasic enclosure, therefore, these may not work well in tight spaces where other electronic components are close by, especially if the breaker's orientation must be altered to adhere to the polarity restrictions.

will not fit in any standard fuse holder

These automatic thermal circuit breakers are an essential and reliable safety upgrade for any high-powered children's electric vehicle, specifically for double-drive or four-wheel drive models. Rated for 15 Amps and supporting up to 250V AC or 32V DC, they provide immediate peace of mind by automatically cutting off the circuit whenever the load exceeds the rated current, effectively protecting the vehicle's internal wiring from damage. The automatic reset feature is a huge convenience, eliminating the need to manually replace blown fuses after an overload event. With two breakers included in the package, this set offers excellent value and durability for maintaining the safe operation of motorized toys.
