Bussmann CBC-10 Automotive Circuit Breaker 10 A

SKU CH-VBWF-51EPA

Plug-in 10 A automotive circuit breaker with automatic reset, SAE J553 rated for trucks

  • Reliable overload protection with 10 A current rating
  • Automatic reset restores power without manual intervention
  • SAE J553 compliance meets automotive industry standards
  • Compact plug-in design fits tight surface-mount spaces
  • 5 kA interrupt capacity handles high fault currents

10 A Automotive Circuit Breaker

The Bussmann CBC-10 is a 10 A heavy-duty circuit breaker designed for 14V DC truck electrical systems. It carries a 1.5 kA interrupt rating at 14V DC and meets SAE J553 standards. The automatic reset function restores power after a fault clears without manual intervention.

Verify voltage and mounting before fitting

Confirm the vehicle system operates at 14V DC and that the plug-in surface mount matches the panel layout. The breaker uses #10-32 stud terminals, so existing wiring must accommodate that stud size. Ensure the 13/16 in depth and 1 1/4 in width fit the available space.

Thermoplastic and metal housing with automatic reset

The combined thermoplastic and metal housing resists vibration in truck environments. Stud terminals provide a secure bolted connection that resists loosening over time. Automatic reset reduces downtime by restoring the circuit once the overload condition ends.

Questions about this item

Does the CBC-10 come with the #10-32 mounting hardware or must I buy studs and nuts separately?

The breaker has #10-32 stud terminals; mounting nuts and washers are not included and must be sourced separately.

I see only a 10 A version listed — are other current ratings available in the CBC series?

The CBC series includes multiple current ratings; this listing is for the 10 A model only.

What does the 1.5 kA interrupt rating at 14 V DC mean for a truck electrical system?

It means the breaker can safely interrupt up to 1.5 kA of fault current at 14 V DC, protecting wiring and components in heavy-duty truck circuits.
