    Abstract: A support for anchoring a trip unit of a circuit breaker to a base thereof to prevent separation of the trip unit from the base during a short circuit fault. The support has top-facing two locking tabs that snap into place behind a wall in a lug-receiving area of the base. The support also has an opening through which a terminal of the trip unit is received snugly. The locking tabs keep the support in place and prevent forces produced by gasses during a fault from forcing the trip unit away from the base. The terminal, attached to the trip unit, is retained by the opening, which transfers upward forces to the top of the support, which is positioned against a top section of the base. The snug fit by the terminal through the opening and retention of the support in the lug-receiving area during a fault increases post-fault dielectric performance.

The telescopic rod can be locked by a locking element so that the shutter plates, which can be moved by sliders, can no longer be displaced.

  • Publication number: 20110013345
    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.

    Abstract: A drawout system with an interface proving a lower ingress protection rating is provided. The system includes a flange mounted to a door. A sleeve is movably mounted to the door adjacent to the flange. As the circuit breaker is moved from a racked-in position to a test position to a racked-out position, the sleeve moves with the circuit breaker and avoids creating exposure to electrical components within the drawout. The drawout system allows the operator to operate the circuit breaker with the door open or closed.
