The new Pro Save W offers all the same great protection as the other Euro models but in a new waterproof plastic package with stainless steel hardware an very low footprint, made possible by a new induction fan cooling system which only operates when the unit is in a major fault condition, this ensures that in full fault condition the product does not exceed 90 deg C, during tests the product 24 hr fault temperature was sustained well below.

The new range also offers two LED warning lights. The two warning lights indicate the following:

• To indicate if there is a break through fault, ie the earth voltage has exceed the ability of the device to protect the boats system ( very rare this would ever be the case ) Unit rated to sustain full fault + 20% current for 24 hours at 50 deg C & not exceed 90 deg C
• Total failure due to massive short circuit way beyond the products ability to protect, and the product has failed and the boat and personnel are in danger. If a boat and shore power systems have normal conventional safety devices ( Fuses-trips etc ) installed its simply not really possible to destroy this product under any fault condition without some other underlying event or an incorrectly rated product on the circuit. The over engineered aspect of this product cannot be overstated.
