What does "marine rated" mean?

Marine rated means the circuit breaker is designed to operate reliably in environments exposed to moisture, vibration, and temperature variation. It features weather-resistant construction suitable for boats, caravans, and 4WD applications.

What does "Type III ignition protected" mean?

Type III ignition protection means the breaker is designed to prevent sparks or arcs from igniting flammable vapours. This makes it suitable for installation in engine compartments and marine environments where fuel vapours may be present.

Is this a manual reset breaker?

Yes. The CB255 series is a manual reset breaker with a push-to-trip function. Once it trips due to an overload, it must be manually reset after the fault is cleared.

Can this replace a fuse?

Yes. A resettable circuit breaker like the CB255 can replace a fuse of the same amperage rating. It provides overcurrent protection without requiring fuse replacement after a trip.

Can this be used in 12V and 24V systems?

Yes. The CB255 series is rated up to 32V DC, making it suitable for both 12V and 24V DC systems.

How do I choose the correct amp rating?

Select a breaker rated slightly above the normal operating current of the circuit, but below the maximum current rating of the cable. Always match protection to cable size.
