Automotive Circuit Breaker 15 A

The Bussmann CBC-15B is a heavy-duty automotive circuit breaker rated at 15 A for 14 V DC systems. It features an automatic reset function and a plug-in surface mount design with stud terminals. The unit meets SAE J553 standards and is built with a thermoplastic and metal housing. It is intended for electrical circuit protection in compatible trucks.

Suited for 14 V DC truck circuits

This breaker suits technicians and fleet maintainers protecting 14 V DC accessory circuits in trucks where automatic reset is preferred. It accepts ring terminals on #10-32 studs for secure connections. It is not suited for systems operating at voltages other than 14 V DC or for applications requiring a manual reset mechanism. Buyers needing a different current rating should select another model.

15 A current rating at 14 V DC

The single specification that decides fitment is the 15 A current rating combined with the 14 V DC voltage rating. The breaker interrupts up to 1.5 kA at 14 V DC and uses #10-32 stud terminals for ring terminal connections. Verify that the circuit requires exactly this amperage and voltage before installation. The automatic reset and SAE J553 compliance complete the critical profile.

Questions about this item

What plug-in space and stud size does the 15 A CBC-B breaker need?

It fits a plug-in surface mount and uses a #10-32 stud for the ring-terminal connection.

How is the breaker installed and what step is often missed?

Insert the plug-in body into the panel, then torque the #10-32 stud to secure the ring terminal; skipping the stud torque leaves a loose connection.

When should the 15 A CBC-B breaker be replaced?

Replace it if the automatic reset no longer restores power after a fault or if the thermoplastic/metal housing shows cracking or heat damage.
