  • Patent number: 8115123
    Abstract: A configurable circuit breaker is disclosed which is, for example, applicable for medium voltage range, with flexibility in configuration, based on the electrical and mechanical constraints. The circuit breaker can include multiple poles, which can be fitted on a shaft at desired positions, using clamping, dowelling, bolting or other types of connections. An epoxy frame can mount the circuit breaker on a truck horizontally or vertically, by mounting inserts and the clamping mechanism. Side sheets of the pole allow internal access. Flexible contacts and the vertical slots enable adjustability in the incoming and outgoing distances, as per design constraints. A tulip contact can be provided for mounting incoming/outgoing conductors. A common actuator can be mounted anywhere on the shaft, via the movable contact or on any of the poles, which are robust enough.
