Product Details

The WirthCo 31117 is a 40 amp auto-reset circuit breaker with stud-type mounting designed to protect electrical circuits from damage caused by overload or short circuit conditions. When an overcurrent condition occurs, the breaker automatically trips to interrupt power flow, then automatically resets once the fault is cleared and the breaker cools down, eliminating the need for manual intervention.

Key Features:

  • 40 amp current rating for medium-duty electrical circuit protection
  • Auto-reset functionality automatically restores power after tripping
  • Stud-type mounting terminals for secure, reliable connections
  • Complies with SAE Standard J553 for automotive circuit breakers
  • Thermal trip mechanism protects against sustained overloads
  • Ideal for automotive, marine, RV, and powersports applications

This circuit breaker provides reliable overcurrent protection for 12-volt DC electrical systems. The stud terminals allow for direct wire termination using ring terminals, making installation straightforward. SAE J553 compliance ensures the breaker meets industry standards for performance and reliability in mobile applications.

Fast and easy shopping

good price heavy switch

Easy to order and find parts

great shopping experience but from my online buying experience is that if you place an order of 200 or more shipping should be free but that's just my opinion

Quick, straightforward, like Amazon pay

Very satisfying. I am thankful that your company also offered me a discount from the very beginning. It shows commitment on your behalf to satisfy your customers.

They have the best prices and very fast shipping

So far so good.

So far process has been very easy.

Good so far

Processed and shipped fast. I was a little upset with them shipping my Eibach springs in the Eibach box, and not repackaging it. Everyone could see the box, and knew what was in it. But this will not stop me from ordering again.

Fast and easy.

Super fast shipping, exactly as ordered, no drama, problems or complications
