Product Details

The Bussmann CBC30 is a Type I heavy-duty automotive circuit breaker designed to provide reliable overcurrent protection for 12-volt and 24-volt DC electrical systems. Rated for 30 amps, this thermal circuit breaker automatically resets after cooling when an overload condition is cleared, eliminating the need for fuse replacement.

Key Features:

  • 30 amp continuous current rating for heavy-duty applications
  • Type I automatic reset design - breaker resets automatically after cooling period
  • Stud terminal configuration for secure, high-current connections
  • Thermal protection prevents damage from sustained overcurrent conditions
  • Suitable for automotive, marine, RV, and other 12V/24V DC systems
  • Compact design for easy installation in tight spaces
  • Durable construction for long service life in demanding environments

The CBC30 uses a bimetallic element that trips when excessive current generates heat, then automatically resets once cooled. This makes it ideal for protecting motors, winches, lighting circuits, and other accessories where temporary overloads may occur. The stud terminals provide a robust mechanical and electrical connection for high-amperage circuits.

Best price I could find for a programmer for my Jeep. Took a few days for the order to process as shipped but they did notify me that order would process within 24 business hours.
