All devices which are set in panelboards, on their morphology it is possible to divide into cabinet-type and module. Cabinet-type wares present from itself devices, whose a form and sizes is determined by a functional necessity and are not standardized for different producers. Such devices are assembled in a shield, as prvilo individually on an assembling plate. Among such devices are circuit breakers on large (more 125A) currents, most watthourmeters, knife-switchs and proch.. The domestic introductory automat of AP50 (to justice for the sake of, very reliable) can the example of cabinet-type device with which certainly every user clashed in the way of life serve is a black rectangular box with two buttons in a right lower corner – red and white. Occupying much place, such devices force to increase the sizes of shield, therefore, wherein it is possible, in place of them it is expedient to use module devices.

Module devices which are set in panelboards are name 2 apartment life download devices, whose basic adjustings sizes are standardized and does not change from a producer to 2 apartment life download the producer (as a rule). Such devices are set in shields on the special metallic type, named DIN -reykoy 35 mm, horizontally in a row. Thus, they form as though single 2 apartment life download unit (rice 3) and can be closed by a single closing panel, abandoning access 2 apartment life download to custom devices controls. Sizes of the modules, subject to standardization 2 apartment life download followings: width 17,5- 18 mm . An exception is made by such now exotic things, as module circuit breakers of production of the Tiraspol’skogo factory of VA 60-2 apartment life download breadthways 12,5 mm . These devices deserved separate mention in connection with that at the limited sizes of shield they allow to place greater kollichestvo automats. depth from the plane of internal 2 apartment life download side of closing panel to the plane of fastening are 58 mm. A general height of 2 apartment life download the module is no more than 96 mm. central location and width of vytupayushchey part, bearing 2 apartment life download on itself the organs of control and management (it allows to use a standard closing panel for the module 2 apartment life download devices of different producers). Devices can have a different width, depending on setting, but this parameter is always multiple to the width 2 apartment life download of one module – 17,5- 18 mm. We will be stopped a bit more detailed for destiny and maintenance of shield 2 apartment life download equipment. In general case, this equipment is intended for a reception, distributing and account of electric power, 2 apartment life download management users, defence of 2 apartment life download lines and users of electric power at overloads and short circuits, users from a defeat an electric current 2 apartment life download.
