> The Relay box is a polarity inversing gear that is placed between the power supply (battery + circuit breaker) and the drive unit. It inverses the rotation direction and therefore enables to furl in or out. The foil sections turn at constant speed.
> Waterproof circuit breaker (included) : turns off the furling gear in case of overheating (due to a Genoa sheet not released for instance).
The relay box and the 30A/60A circuit breaker are included in the electric headsail furler standard kit.
