Sea-Dog Thermal Breaker Boot 420839-1 - Splash Guard Cover for Circuit Breaker Terminals

The Sea-Dog Thermal Breaker Boot (420839-1) is a protective cover designed to shield the terminal posts of a thermal circuit breaker from spray and moisture exposure aboard a boat. It slips over the exposed terminal connections on a thermal breaker, helping to guard the electrical contacts and reduce the risk of corrosion or accidental contact in a marine environment. This boot ships as a set of two (sold as a pair) and is packaged by the manufacturer in cases of 10 pairs.

Compact and lightweight, the boot measures 6 x 2 x 2 inches and weighs just 0.016 pounds, making it an easy, low-cost addition when installing or servicing a thermal circuit breaker on a boat's electrical panel. Because it is a genuine Sea-Dog part, it is built to the same fit and material standards as the breaker terminals it is designed to cover.
