Abstract:
A controller for an industrial automation system includes a main module having a housing, which can be fitted onto a DIN rail via a base, at least two printed circuit boards arranged in the housing, and a heat sink also arranged in the housing and connected with the base. One of the circuit boards is a backplane bus printed circuit board, which provides a backplane bus, and the other is a main printed circuit board. The heat sink is attached to at least one of the printed circuit board to cool its components.
Abstract:
Motor control centers have units or bucket assemblies with a spring-loaded front panel attached to a housing of the unit by a laterally extending metallic shaft that allows the front panel to pivot open about a long axis of the shaft. When closed, the bottom of the front panel slidably receives and is in abutting contact with the shaft which provides an electrical ground.
Abstract:
A module latching arrangement for mounting and dismounting on a generally U-shaped support rail at least two module base bodies arranged orthogonally above and extending transversely across the support rail, each of the base bodies having a pair of bottom corner portions arranged on opposite sides of the support rail. At least one foot member is connected for horizontal longitudinal sliding movement relative to one of the base body corner portions relative to the adjacent support rail horizontal flange portion. A lateral displacement arrangement on the foot member is operable, when the foot member is displaced from a locked position toward an unlocked position relative to the support rail, to displace the first base body laterally away from an adjacent second base body mounted on the support rail. The foot member is latched in either a locked or an unlocked position relative to the base member.
Abstract:
The invention relates to a connector element for two installation breakers, adjacently attached with the broad faces thereof in contact, in particular, power breakers or residual current breakers, the housings of which are each formed from two dished housing pieces. The connector element comprises an approximately cylindrical base body with a first external diameter on the front side of which two radially-sprung, axially projecting first and second expanding arms are moulded. The external contours of the spreader arms lie on a cylindrical outer surface, the external diameter of which is smaller than the first external diameter of the base body. The free ends thereof comprise radially projecting lugs on opposed external lines, which, in the assembly state, clip behind recesses on the housings, for connection by means of the connector element, of adjacent installation breakers. A sprung spreader element is mounted between a first and second spreader arm such that the spreader element supports the sprung spreading of the spreader arms, and which impedes the sprung contact of the first and second spreader arms with each other.
Abstract:
A multiple switch includes a pair of switch units arranged in a row and forming a common actuating surface. The switch units are provided with uniform module housings (12). The adjoining module housings (12) are mechanically rigidly coupled to each other by a connecting element (14).
Abstract:
Adding "plug in" surge protective devices, particularly in loadcenters already installed and in use, reduces the number of "stab spaces" available for circuit breakers. A breaker may be combined with a surgeprotector, both connected in parallel to a "stab" on the load center bus, or having a common bus contact within the combination breaker/protector, is thus both desirable and frequently necessary. The apparatus provides greater flexibility of location for a "plug in" surge protector in a loadcenter by making the surge protector adaptable for mounting in single "thick" or "thin" breaker spaces, and for combining a "thin" breaker with a "thin" surge protector for use within a single "thick" breaker space in the loadcenter. The invention provides a method for separating a defective breaker or surge protector from the combination and for easy replacement of the defective element. Surge protectors may thus be added to the loadcenter, one for each bus it is desired to protect, without requiring additional "stab spaces."
Abstract:
A latching foot assembly for latching electrical components on a support rail includes first and second latching feet or members each including first and second resilient clamping portions between which the support rail is latched or grasped. A latching finger is integral with the first clamping portion of each latching foot. The first clamping portions of the latching feet are connected in interlocking fashion. The latching finger of the first clamping portion of the first latching foot has a support surface for supporting the support rail in a latched state. The support surface extends farther in the direction of the second clamping portion than a support surface for supporting the support rail in the latched state of the latching finger of the first clamping portion of the at least one second latching foot.
Abstract:
A power supply module for intelligent electronic apparatuses and capable of transforming the energy of the LV network and of a battery into energy that can be used by said apparatuses is produced to serve as support for said apparatuses. In particular, for a use in a telecontrol equipment item, the casing of the power supply module is flat, can be installed on wall-mounted DIN rails, and includes, on its front face, a DIN rail for fixing the apparatuses that it powers, that is to say other functional modules of the equipment. The casing also includes an apron for the connections. Preferably, the power supply is produced by series connection, and the power supply module includes a port dedicated to external communication via a module of the equipment.
