BussmannCB185-50 CB185 Series Automotive Circuit Breaker (Plug In Mounting, 50 Amps, Blade Terminal Connection)

Protects my 12v battery charging circuit in EV conversion S10. Had 50a blade fuse which always heated up & connections corroded = poor connections. Circuit breaker has screw terminal connections for solid connection. Have used same CB (under hood) for my elec power steering motor for 4 years & has always worked fine. I stick with tried & true brand names for critical elec components = you DO get what you pay for!!

Installed on a semi for an electric tarp system. It is a quality product and exactly as described.

Bought this to bypass a troublesome 50a fuse on my APU. A right pain removing the cover to the Thermo King APU and each time the fuse blew it was $5 - an expensive fuse !! Biggest problem was wrestling with the cover of the APU. $40 or $50 each time to get a mechanic to do it. Tapped into the fuse holder and ran it up into the sleeper. Drilled a hole and screwed it onto the sleeper berth kicker panel. No further problems. The APU still charges the batteries ok - this was a concern of mine. Hasn't interfered in daily life at all except that you must be careful not to accidentally brush by the red reset button. That will disconnect the apu and result in a flat battery pack.

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.

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.

I have used these circuit breakers before on some of my higher amperage items (75 amps and 100 amps) and was looking forward to being able to use the 50 amp version of this circuit breaker. On this application, I used the 50 amp circuit breaker in place of a HEAVY DUTY fuse in my RV on a circuit that was giving me trouble. As I ran down the "short", the circuit breaker tripped as it should have and it didn't cost me $5.00 each time like the heavy duty fuses. Once I ran down the issue with the circuit (frayed wire, of course), I left the circuit breaker in place. These are my "go to" replacements when fuses and fusible links go out and I will continue to use them on my RV, boat, etc.

I purchased this to replace the inline fuse to my trolling motor when I rewired my old fishing boat. Like others have stated, it's nice to have the ability to kill the circuit by pushing in the red button and have the safety of circuit protection. This item proved its value the first week I had it installed when my (very old) trolling motor foot controller went up in smoke and the breaker tripped to limit further damage. Now I get to purchase the new trolling motor that I wanted anyway, without having to buy a new boat to go with it!

I use my 50 amp Bussmann breaker for my Minn Kota 101 lb thrust trolling motor. The great part about it to me is that by pushing the red button on the top it opens the circuit. So I don't have to install an on/off switch along with the breaker. When I want to cutoff power to my trolling motor I just push the red button and the circuit opens, shutting off power to the motor. To turn it back on/close the circuit, you just have to slide the little black arm back into it's "on" position and you're back in action.Plus it's a great safety feature.
