Bussmann CB222 Automotive Type II ATC Circuit Breaker, 12VDC

Bussmann CB222 Automotive Type II ATC Circuit Breaker, 12VDC

The Bussmann CB222 is an automotive-style circuit breaker built on the Type II ATC blade footprint for direct drop-in use in standard ATC fuse blocks and panels. Rated 12 Vdc, it is housed in a UL-rated 94V-0 flame-retardant thermoplastic body with a metal cover — gold on Type I units, silver on Type II & III units — and is available in 10A, 15A, and 25A ratings so it can be matched to a range of 12V circuit loads. Because it resets after a fault clears rather than requiring replacement like a one-time fuse, this Bussmann circuit breaker is a practical upgrade for RV, automotive, marine, and off-road 12V wiring where circuits are cycled or serviced in the field.

Key Features

• Type II ATC Footprint: Standard automotive blade-style profile for compatibility with common ATC fuse block, panel, and holder layouts.
• 12 Vdc Rating: Engineered specifically for 12 Vdc automotive and RV electrical circuits.
• Amp Rating Range: Available in 10A, 15A, and 25A ratings, allowing the correct breaker to be selected for the circuit load being protected.
• Durable Housing: UL-rated 94V-0 flame-retardant thermoplastic construction for dependable, code-conscious performance under vibration and heat.
• Metal Cover: Gold metal cover on Type I units or silver metal cover on Type II & III units for a secure, corrosion-resistant contact surface at the blade terminals.
• Resettable Protection: Automotive circuit breaker construction allows the circuit to be restored once the fault clears, reducing the need to keep spare fuses on hand.
• Drop-In Replacement: Blade footprint matches standard ATC-style fuse positions, simplifying upgrades from single-use automotive fuses to resettable protection.
