Bussmann CBC20B 20 Amp Type I Heavy Duty Automotive Circuit Breaker

The Bussmann CBC20B is a Type I heavy-duty automotive circuit breaker designed for reliable overcurrent protection in 12-volt DC electrical systems. This automatic-reset breaker features a 20 amp rating and is ideal for protecting high-current circuits in cars, trucks, RVs, marine vessels, and other automotive applications.

Key Features:

• 20 amp rating at 14 volts DC for heavy-duty circuit protection
• Automatic reset design eliminates the need for fuse replacement
• 10-32 threaded stud terminals for secure, permanent connections
• 90-degree angle mounting configuration with crosswise bracket for flexible installation
• Type I automotive-grade construction for durability and reliability
• Thermal trip mechanism protects against sustained overloads

This circuit breaker mounts at a 90-degree angle using the included crosswise bracket, making it easy to install in tight spaces or on bulkheads. The stud terminals accept ring terminals for solid electrical connections. When an overload condition occurs, the breaker trips automatically and resets once the fault is cleared and the breaker cools down, providing convenient protection without manual intervention.
