Understanding circuit breakers on commercial trucks

Phillips Industries has published its first tech tips of the new year. This month’s issue tackles the fundamentals of circuit breakers.

The company defines a circuit breaker as “an automatic device used to stop the flow of current as a safety measure. It will prevent damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected.”

In the trucking industry, Phillips Industries says two different types of circuit breakers are used — auto-reset and manual reset. This month’s issue then offers descriptions of the circuit breakers and how they work, as well as useful circuit protection information.

Other tips found in the issue include the note that Type I circuit breakers are used for applications such as noseboxes whereas Type III circuit breakers are used for other high amperage draw applications like liftgates.
