My 80's camper had a 2amp breaker on a 15 amp line for the operation of a fridge line. I couldn't keep the breaker from blowing. Same maker (Carling Switch) the distributor seems to be Blue Sea Systems. Old smaller amp breaker may have been sufficient with the original fridge but the last owner upgraded and the breaker could no longer sustain the power requirements. Bought this 5 amp (2 amp was impossible to find anyway) and fridge runs beautifully. Went in easy, identical to the originals. I may change up all my breakers with this brand (they are all original) just for the heck of it.

Received 2 Blue Sea system circuit breakers, one missing a small plastic bag with black small screws for mount on panel.
