Tubular Circuit Breaker Custom Parts

As the name suggest these Lugs are specially made for terminating large cables to circuit breakers. Since Flash over distances have reduced, the connecting tunnel in breakers have become narrower. Thus fitting lugs in 150A to 250A breakers has become a problem because the palms of the conventional lugs are too wide. To counter this problem we use a special extrusion process to make a narrow palm that can easily be inserted in the connecting tunnel. The lugs also have a bell-mouth on the barrel opening to facilitate easy-entry of the conductor.
