Terminal blocks in the use of the process of doubt?

With the requirements of motor operating conditions and motor protection, motor winding temperature, bearing temperature, motor vibration and other test components, quickly entered the motor manufacturing industry, such as PT00 and PTC is the most widely used temperature measurement components. As a result, terminal blocks were developed, which are wiring devices that connect motor temperature measurement components with the customer's control terminal. Terminal blocks are commonly used in electrical engineering, which is a series of combined wiring fixtures, the number of terminals in each row is different, according to the technical parameters of the project to determine the model.

1, what is the use of grounding terminal row in the distribution box? Answer:The grounding terminal is a special terminal for the ground line, now our electricity is a three-phase four-wire system. Zero and ground are separated. The ground wire is generally connected to the socket ground to protect the safety of electricity! 2, what is the use of terminal blocks? Answer: The wire connection between different devices, the need for terminal blocks, some plug-ins (modules) also need terminal blocks. 3, electrical cabinet when the need for wiring terminal blocks? Answer: To an installation unit as a boundary, in and out of this unit will need a line terminal block.

4, the terminal block model model 4EN represents what means? Answer: 4EN indicates that the contact area of 4 square millimeters. 5. terminal block are what role ah? Answer: Convenient wiring; such as in the installation of power distribution cabinets, cabinet doors on the signal lamp or meter should be on the terminal. Check the line for convenience; easy to measure when a fault occurs. Node expansion; node expansion of the same line number. 6, in the substation design, how to choose the transformer and terminal block? Answer: the capacity of the transformer to be calculated, too large or too small are not; terminal row to ground distance is generally not less than 350mm, the current circuit must be used OT wiring current test terminals.
