Angle Adjustable Rear Post for Molded Case Breakers

Abstract

An adjustable rear post connector adapted to connect a circuit breaker to a busbar is disclosed. The back post connector is rotatably adjusted to contact a corresponding bus bar while minimizing stress applied to the back post connector when connected to the bus bar. Post connectors include post and post adapters. The rear column includes a column sheet and a column base. The rear post adapter includes an adapter base and an adapter mounting portion. The adapter base includes a plurality of attachment holes for attaching the post base to the adapter base with fasteners. The plinth includes a plurality of circumferentially extending slots relative to the central axis of the plinth for connecting the plinth to the adapter base with fasteners and allowing the plinth to align with the adapter base in a circumferential direction relative to the central axis. There is a degree of location flexibility.

Description

technical field [0001] The present invention relates to an adjustable rear stud connector suitable for connecting a circuit breaker to a bus bar. In particular, the present invention relates to adjustable rear post connectors that are rotatably adjusted to contact corresponding bus bars while minimizing stress applied to the rear post connectors when connected to the bus bars. Background technique [0002] In the current market, Molded Case Circuit Breakers (MCCBs) are often connected to the busbars of the appliance by means of circuit breaker rear post connectors, such as large copper and / or aluminium bus connections connector (bussingconnector) or large cable. [0003] Conventional circuit breaker rear post connectors have the disadvantage that the connection between the circuit breaker rear connector and the busbar is often stressed due to poor alignment of the contact surfaces of the rear connector and the busbar. Using fasteners to connect or secure the contact surfac...

[0003] Conventional circuit breaker rear post connectors have the disadvantage that the connection between the circuit breaker rear connector and the bus bars is often stressed due to poor alignment of the contact surfaces of the rear connector and bus bars

In the past, Siemens, as well as some competitors, offered adjustability of the rear post in 90 degree increments, often making it difficult to make a reliable connection without applying undesired forces to the unit
