Circuit breaker, circuit breaker terminal lug cover, and method of protecting a terminal lug

摘要

A circuit breaker terminal lug cover is structured to mechanically secure to a circuit breaker terminal lug and protect the terminal lug from degradation or corrosion. The terminal lug includes a number of terminal lug screws capable of securing a number of cables to the circuit breaker. The terminal lug cover includes a plurality of sides structured to carry heat away from the terminal lug or deflect ionized gases away from the terminal lug. At least one of the sides includes a number of securing members structured to mechanically secure the terminal lug cover to the circuit breaker terminal lug. One of the sides includes an access hole permitting access to the number of terminal lug screws.

1. A circuit breaker terminal lug cover structured to mechanically secure to a circuit breaker terminal lug and protect the terminal lug from degradation or corrosion, the terminal lug including more than one terminal lug screw capable of securing a number of cables to the circuit breaker, said terminal lug cover comprising:
a plurality of sides structured to carry heat away from the terminal lug or deflect ionized gases away from the terminal lug, said plurality of sides comprising:
a first side,a second side opposite and spaced from said first side,a third side extending from said first side to said second side, said third side including a single access hole permitting access to at least one of terminal lug screws, anda fourth side extending from said first side to said second side, said fourth side being normal to said third side, wherein at least one of said first side and said second side includes a number of securing members structured to mechanically secure the terminal lug cover to the circuit breaker terminal lug, and wherein the access hole is centrally disposed on said third side and spaced from each of said first side and said second side.
