Patent number: 8514041Abstract: A mounting unit for an electromagnetic contactor can prevent erroneous mounting of a non-mountable unit in a state in which a mountable unit is mounted on a case-side mounting portion, and a connection structure of an electromagnetic contactor uses the mounting unit. A mounting unit (3) for an electromagnetic contactor can be mounted on electromagnetic contactors (2a, 2b) having on a unit attaching portion (6b) a contactor-side mounting preventing portion (6f) that prevents mounting by engagement when a non-mountable unit, which cannot be mounted, is mounted. In the mounting unit (3), a unit main body (39) is provided with a mounting preventing transfer member (51) that forms a unit-side mounting preventing portion (54) that engages with a contactor-side mounting preventing portion (6f) when mounted on the electromagnetic contactors (2a, 2b) and prevents mounting of the non-mountable unit on a unit mounting portion (3g) onto which the non-mountable units (5a, 5b) are mounted.Type: GrantFiled: September 13, 2010Date of Patent: August 20, 2013Assignee: Fuji Electric FA Components & Systems Co., Ltd.Inventors: Yasuhiro Naka, Koji Okubo, Kouetsu Takaya, Kenji Suzuki

Patent number: 8487204Abstract: The present invention relates to a switching device, in particular an automatic switch, a disconnector or a contactor, with high dependability, for use preferably in low voltage electrical systems. In particular the invention relates to a single-pole or multi-pole double break switching device for low voltage systems comprising, for each pole, at least a first pair of contacts and at least a second pair of contacts. Each pair comprises a stationary contact and a movable contact which can be reciprocally coupled/decoupled at the level of a first breaking cavity and a second breaking cavity respectively. Said cavities are defined inside a casing which comprises a first surface with respect to which an internally hollow portion protrudes, said internally hollow being integrally made with at least one portion of the casing.Type: GrantFiled: October 28, 2008Date of Patent: July 16, 2013Assignee: ABB S.p.A.Inventors: Edoardo Scola, Eligio Zanchi

Patent number: 8487725Abstract: An extinction cover (5) is mounted on a case (4) thereby sealing an extinction chamber (S). This extinction cover has an engaging-force-increased portion (5c1) which strengthens the force of engagement with the case, and an engaging-force-decreased portion (5c2) which weakens the force of engagement with the case. In response to an increase in internal pressure in the extinction chamber due to arc gas generation, the engaging-force-decreased portion establishes disengagement of the case and provides a gap (27) with the case, for linking the extinction chamber to external air, and the engaging-force-increased portion maintains engagement with the case.Type: GrantFiled: June 14, 2010Date of Patent: July 16, 2013Assignee: Fuji Electric Fa Components & Systems Co., Ltd.Inventors: Kouetsu Takaya, Koji Okubo, Yasuhiro Naka, Kenji Suzuki

Patent number: 8487724Abstract: A molded case circuit breaker having a trip unit with one or more integrally formed dielectric protrusions that are configured to slidably interconnect with corresponding dielectric members of the base when the trip unit is secured to the base. The dielectric protrusions extend from dielectric walls located between adjacent enclosure chambers that house the current transformers and are configured to remain in contact with the dielectric members of the base as the trip unit is being moved with respect with the base. By remaining in contact to one another while the trip unit is moved with respect to the base, the dielectric protrusions, along with the dielectric members, maintain a strong dielectric barrier within the exterior spaces between the CT enclosure chambers, thereby preventing debris from traveling between and accumulating on the trip unit and the base.Type: GrantFiled: November 23, 2010Date of Patent: July 16, 2013Assignee: Schneider Electric USA, Inc.Inventor: Dennis W.

Patent number: 8466759Abstract: A reversible unit (10) is attached by being mounted over a pair of adjacently disposed electromagnetic contactors (1a) and (1b). The reversible unit (10) includes a pair of interlock plates (11) and (12), a lock piece (13), and a unit case (10b) accommodating the pair of interlock plates (11) and (12) and the lock piece (13). The lock piece (13) rotates in a first direction with the movement of one of the interlock plates (12) in a turn-on operation of one of the electromagnetic contactors (1a) to prevent the movement of the other interlock plate (11), and rotates in a second direction different from the first direction with the movement of the other interlock plate (11) in a turn-on operation of the other electromagnetic contactor (1b) to prevent the movement of one of the interlock plates (12). The unit case (10b) is provided with a lock piece display window (10g) which allows determination of the rotation of the lock piece (13) in the first direction or the second direction.Type: GrantFiled: September 13, 2010Date of Patent: June 18, 2013Assignee: Fuji Electric FA Components & Systems Co., Ltd.Inventors: Kouetsu Takaya, Koji Okubo, Yasuhiro Naka, Kenji Suzuki
