摘要： A gas insulated switchgear is configured including phase-A, phase-B, and phase-C breaker units. For example, the phase-A breaker unit includes breakers connected in series in a horizontal first direction, disconnectors annexed on the breaker, disconnectors annexed on a breaker, and disconnectors annexed on a breaker. The disconnector is connected to a main bus that extends in the first direction, and the disconnector is connected to a main bus that extends in the first direction. Each of the disconnectors on the breakers is arranged while a longitudinal direction thereof is set to a second direction orthogonal to the first direction so that a switching direction of the disconnector is equal to the second direction. Thereby, the length of the main buses can be shortened, and an interphase distance and a breaker-to-breaker distance can be reduced.

摘要： 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.

摘要： At least one embodiment of the invention provides that, for a closing apparatus for a part rack withdrawable via V-shaped rod assemblies, the closing apparatus includes at least one pin formed on rod assemblies or as part of them, each pin engaging in a slot in an actuating element. Owing to the use of the slots, the actuating element can be formed as a rigid body, with the result that no frictional forces need to be overcome when inserting a circuit breaker into a withdrawable-part rack with the closing apparatus according to at least one embodiment of the invention. With the closing apparatus according to at least one embodiment of the invention, a locking element can have a particularly simple design: it can be guided in the actuating element.

摘要： A load center is equipped with a neutral phase conductive rail with breaker mounting and retention features providing automatic neutral connection for a plug-on mounted AFI and/or GFI circuit breaker. Breakers may be designed to have specific interfaces to the breaker mounting and retention features of the load center rails. The neutral rail may have two pieces including a breaker undercut positioning rail shorted to a standard neutral rail, or a neutral rail may be designed to have all mounting features integrated therewith. The new panel is compatible with non-AFI and non-GFI breakers.
