Bussmann CB212 ATM Footprint Automotive Circuit Breaker, 14 Vdc

Bussmann CB212 ATM Footprint Automotive Circuit Breaker, 14 Vdc

The Bussmann CB212 is a Type II ATM footprint automotive circuit breaker built for 14 Vdc electrical systems in RVs and automotive circuits. Housed in a Grey UL-Rated 94V-0 thermoplastic shell with a silver metal cover, this circuit breaker delivers reliable overcurrent protection in a compact, blade-style footprint that drops into standard ATM/mini fuse block layouts without any change to the surrounding wiring harness. The CB212 platform is available in Amp Rating options from 10A to 30A, so installers, upfitters, and RV technicians can match breaker capacity to the specific circuit load without changing the mounting footprint or reworking the fuse block. Choosing the correct amp rating for the connected load helps protect wiring and downstream accessories from overcurrent damage.

Key Features

• ATM Footprint: Type II blade-style footprint fits standard ATM/mini automotive fuse and breaker blocks for straightforward installation and drop-in replacement.
• Amp Rating Range: Available in 10A, 15A, 20A, 25A, and 30A ratings so the breaker can be matched to the current-carrying needs of individual RV and automotive circuits.
• Voltage Rating: Rated 14 Vdc for low-voltage DC automotive and RV electrical systems.
• Durable Housing: Grey UL-Rated 94V-0 thermoplastic housing resists heat buildup and supports reliable long-term performance in the vehicle electrical environment.
• Metal Cover: Finished with a silver metal cover (Type II) for added mechanical durability over the internal breaker element.
• Resettable Protection: Functions as a resettable circuit breaker rather than a one-time fuse, reducing the need to carry and swap replacement fuses in the field.
• Application-Specific Design: Purpose-built for RVs and automotive circuits where a compact, blade-style circuit breaker is preferred for accessory and branch-circuit protection.
