Part of the 285 Series, this surface-mount breaker features trip-free operation that cannot be held closed after tripping, ensuring safety in overload conditions.

Key Features:

  • 100 Amp rating with 48 VDC maximum voltage (suitable for 12V and 24V systems)
  • Type III manual reset with integrated switch function
  • Trip-free design prevents manual override during fault conditions
  • Visible reset lever clearly indicates open/closed status
  • 3,000 Amp interrupt rating for robust short-circuit protection
  • Rectangular surface mount design with 1/4"-28 threaded studs
  • Compact dimensions: 2.9"H x 1.9"W x 1.78"D
  • Drop-in replacement for 185 Series circuit breakers

This circuit breaker is ideal for applications requiring both overcurrent protection and convenient on/off switching, commonly used in marine electrical systems, RVs, and other DC power distribution panels. The thermal design provides time-delay characteristics to handle momentary inrush currents while protecting against sustained overloads.

Great!

Best price that I could find. It was real easy to order. Placed order on wed received it on Friday, doesn't get much better than that. Product looks great! <br>3/16/2012<br>Ok, product was to big for my setup needed to exchange for smaller product. They are going to charge me a restocking fee of 15% Even when my product did not fall under their conditions. This is crap. False advertisement. I was ok with paying all the extra shipping fees which will be about the amount of the product when it was all said and done. So mad don't think I'm gonna mess with this company anymore. They don't practice what they preach. Beware :(<br>3/20/2012<br>OK, Update number 3.<br>Received E-mail today saying that Autoplicity would now Not Charge Me a 15% restocking fee and they were sorry for the inconvenience. Very Happy Now this is the way to do business. <br>Thanks Rob :)<br>3/21/2012

Great price on my short ram air intake... Actually, best I could find on the Internet. Product shipped the day after the order. Haven't had any problems so far, but it was only shipped just today.

I was very pleased with the way my order was handled. I will definitely use them again.
