This single pole thermal circuit breaker is external ignition protected & weatherproof. Typically used in DC power systems in marine applications (as a main or branch circuit breaker), truck, bus & RV systems, add-on protection for accessories, etc. Some models are sealed for engine compartment and bilge applications.
Type III (Manual Reset): the circuit breaker will trip in response to an over current condition after which a reset
button or lever extends externally to indicate that the breaker has tripped and is in a non-conducting status. The
trip indicator button or lever must be manually activated to return the device to normal operation.
