## Description

Type III switchable, waterproof, flush mount manual reset circuit breakers with 1⁄4-28 threaded stud terminals with SEMS nuts installed, and black reset lever. High amp circuit breakers are typically used in auxiliary and accessory circuits for trucks, buses, RV's and marine applications. All high amp circuit breakers comply with the SAE J1117 standard for ignition protection and have applications in battery charging systems that use battery isolators to manage and protect batteries in multi-battery installations.

Review: Just as good as Minn Kota, but Cheaper - I recently installed a 24v trolling motor on one of my boats. 3 years ago, I installed a 24v trolling motor on my primary boat and purchased the OEM Minn Kota circuit breaker. For this application, I decided to take a chance on the Bussmann breaker since it was a fraction (20%) of the cost of OEM Minn Kota. The breaker arrived and looks identical to the Minn Kota breaker I used on the other boat. Perhaps Bussmann makes breakers for Minn Kota. I don't know and can't verify that. Operation is good and the breaker has a strong mechanical action. I believe it should last for a long time.
Review: Great circuit breaker that can also be used as on/off switch. - I used this for the first time this last weekend and it worked as it says it should. I have it mounted on the top of the battery box on my pontoon boat. After connecting it to the battery via separate battery cables (don't forget you will need them), I connected it to my electric motor an now have no worries about it. Not only does it take the place of a fuse, and it is so much easier than replacing fuses, I also use it as the on and off switch for the motor. Bravo.

### ⭐⭐⭐⭐⭐ Untested as a CB, works great as a switch
*by S***I on August 4, 2023*

I occasionally install fuse boxes in my vehicles for auxiliary equipment, and put one of these in line to the battery. Never had one trip, but I've also never blown one of the fuses in those fuse boxes. So, technically, I've never tested the capability of these as circuit breakers. That being said, they're also useful if you want to turn off all the aux equipment (e.g., you're loaning the vehicle to a family member whom you don't trust to play with all the cool toys, or who doesn't give a rip about the cool toys and would just turn them off anyway, or leaving the vehicle at the mechanic who, again won't appreciate the cool toys and will just turn them off). One thing to be aware of is that you should use the heaviest gauge wire available in conjunction with a circuit breaker like this, as 50 amps is quite a bit of current.
