Question about Difference Between Generator Circuit Breaker

[apittmanii]

Hello. I currently have the circuit breaker depicted in the first photo for a small 2500 watt generator (the one in my hand). It is a single pole circuit breaker. The switch has broken off.

The 2nd photo shows a new one from eBay that has the same specifications (240 volts max, 20 Amps, 25 trip Amps). The only difference are the 3 steel tabs on the back.

1. Can I use the circuit breaker depicted in the 2nd photo if I tape off or clip the steel tabs in the back?

2. What are those steel tabs on the back of the circuit breaker in the 2nd photo?

Thank you,
Allen

I'm guessing it's a set of auxiliary contacts, rated 10 amps at 250 volts according to the label. I would assume them to be isolated from the main contacts, but it would be prudent to check. If they are isolated, you probably don't need to do anything as long as they don't contact anything inside the generator.

Thank you very much, I think you are right. The attached photo is from the manufacturer website. It says

"Isolated electrically from the protector’s circuit, the switch works in unison with the power contacts and provides indication at a remote location of the protector’s on-off status.

Auxiliary switch contacts actuate simultaneously with the main protector contacts, and will open regardless of whether the protector contacts are opened manually or electrically."

So it sounds like these would not be electrically charged from the circuit the breaker is protecting. So as long as they aren't touching any other wires, I should be fine. Let me know if you think differently. Thanks for your help.

I have worked on industrial equipment with aux. contacts on the circuit breakers They are mechanicly tied to the main breaker but not connected electrically in any way. Just make sure they are not cutting into the wiring behind the breaker. If they are in the way cut them off or stick insulated quick disconnects on them if that is the kind of terminal the are. They can be used for remote indication. We had all the breaker aux. contacts wired in series, going to a relay that shut down the whole machine if any breaker tripped
