12V Auto Reset Metal Circuit Breakers without Bracket

Reliable 12V Auto Reset Circuit Breakers for Versatile DC Applications

An auto reset automotive circuit breaker ensures continuous operation in DC applications by automatically recycling during an overcurrent condition, maintaining protection until the issue is resolved. Del City provides a wide selection of 12V auto reset circuit breakers, with ratings ranging from 5 to 50 amps to meet diverse application requirements. These single-pole, stud-mount breakers are available in metal or plastic housings and can be purchased with or without brackets for added installation flexibility. Classified as type 1 breakers, they are suitable for numerous applications, including automotive systems in trucks and buses, as well as portable generators, welding equipment, trolling motors, and multi-outlet power strips. Use with compatible circuit breaker mounting brackets for streamlined installation. Constructed from a durable internal composite alloy, these breakers deflect and separate contacts during overcurrent events, then reset as the device cools. Engineered to perform in challenging conditions, they operate between -10°F and 150°F and are safely stored from -20°F to 200°F. Each breaker includes nuts and washers for easy setup and offers compatibility with popular EATON/Bussmann models, such as 121A06-00M-KA through 121A50-00M-KA, providing reliable interchangeability and quality assurance. Please note that products may be subject to tariff charges at checkout.
