These circuit breakers are rated at 6A 65VDC. The “push-on” terminals may be oxidized due to sitting around for several years. I’ve used them to control and protect radios and other equipment in my car as well as in my shack.
All are “new, old stock” never used. $2.00 each, or all 3 in the picture for $5.00, plus shipping. I have several of these, so let me know how many you would like and we can agree on a total price. Please contact me at the email address on the card in the picture with any questions.
