Automotive Circuit Breaker 30 A

The Bussmann CBP-30BA is a heavy-duty circuit breaker rated at 30 amps for 14V DC systems. It uses an automatic reset function and mounts via a plug-in, surface-style connection with a #10-32 stud terminal. The thermoplastic housing measures 2 inches deep, 1 3/8 inches high and 1 5/16 inches wide. It carries a 1.5 kA interrupt rating at 14V DC and meets RoHS compliance standards.

Suits Truck Electrical Protection

This breaker suits truck circuits requiring 30 A overcurrent protection with automatic reset capability. It is designed for ring terminal connections on 14V DC systems. Buyers needing a different current rating, a manual reset type, or a voltage rating above 14V DC should look at alternative devices. The plug-in mount style also requires a compatible panel or block.

Build Integration Requirements

The unit fits a standard plug-in socket and connects via a #10-32 stud for ring terminals, freeing the installer from soldering or crimping directly to the breaker body. Automatic reset restores the circuit without user intervention after a fault clears. The 1.5 kA interrupt rating handles prospective short-circuit currents on supported truck circuits. RoHS compliance simplifies regulatory approval for the final assembly.

Questions about this item

What stud size does the CBP-30BA use for the power connection?

The breaker uses a #10-32 stud terminal for the ring-terminal power lead.

Will the automatic-reset behaviour interfere with a legacy fuse panel that expects a manual reset?

This unit resets automatically after a trip, so it will not stay open like a manual fuse; the panel must tolerate momentary interruption.

How can I confirm the 30 A rating is holding after installation?

Apply a known load up to 30 A at 14 V DC and verify the breaker remains closed without tripping.
