  • Circuit breaker and reset mechanisms operated through the body
    Patent number: 4965414
    Abstract: An explosion-proof enclosure having a side mounted circuit breaker handle 30, and side mounted motor controller reset handle 38. Bolt holes (46) have been eliminated in the vicinity of breaker handle 30 and reset handle 38 to allow rotation of the handles without reducing the width of explosion-proof joint (44) and without increasing the overall width of the enclosure. Mounting breaker handle 30 and reset handle 38 on the side of the explosion-proof enclosure allows the handles to be aligned, adjusted and tested with enclosure cover either in the open or closed position.
