Product Details

The Sierra CB42240 is a 40-amp automatic reset circuit breaker designed for marine and automotive electrical systems. This thermal circuit breaker automatically resets once the circuit cools down after an overload condition, eliminating the need for manual reset or fuse replacement.

Key Features:

  • 40-amp current rating for high-amperage applications
  • Automatic reset functionality for convenience and safety
  • Ideal for protecting trolling motors, windlasses, and other high-draw electrical equipment
  • Includes stud mounting plate for secure installation
  • Comes with 8 AWG ring terminal for easy wiring
  • Compact design for installation in tight spaces

This circuit breaker provides reliable overcurrent protection for demanding marine and vehicle electrical systems. The auto-reset feature makes it particularly useful for applications where manual access would be difficult or inconvenient. Simply wire inline between your power source and equipment for instant protection against electrical overloads.

Had my product in stock and ready to go. Ordered it at about 1 p.m. eastern time and got an email saying it was shipped out a couple hours later. Can't beat that! Lowest prices I've seen and has plenty of products to choose from. I will be recommending Autoplicity to everyone and anyone.

Great pricing, free shipping, and great product!!! What we got was better than OE for 1/5 the price! Thank you!

They had what I need, and good price, fair shipping and came in 3 days to my house. The box was wrapped very nicely, would definitely buy from them again.
