Description

The Dometic USA 30337 is a 15-amp circuit breaker designed to protect the blower motor in a furnace. This heat-sensitive, resettable device monitors amp draw and trips when an excessive and prolonged amperage draw occurs, indicating a problem.

It is a slow-blow style breaker, externally mounted on Atwood furnaces, ensuring that furnace heat does not affect its operation. This design also prevents short amperage spikes from tripping the breaker prematurely. The breaker is intended to be replaced with one of a similar amperage rating.
