Terminal blocks security seals performance determines its role

In fact, the terminal called terminal blocks . So let us from the terminal 's basic common sense to understand .

1, what the distribution box ground terminal block for?

A: The ground terminal is a dedicated ground terminals , our electricity is now a three-phase four-wire system . Neutral and ground separated. Ground is generally connected to the outlet of the ground line to protect the electrical safety !

2 , and under what circumstances the use of terminal blocks ?

A: The wire connections between different devices , you need to terminal blocks , some plug-in ( module ) also requires the terminal block.

3 , the electrical cabinet when you need terminal blocks ?

A: Take a mounting unit for the sector, and out of the unit will need to wire the terminal block.

4 , terminal blocks Type Type of 4EN What does it mean ?

Answer : 4EN said contact area 4 mm2 .

5 , terminal blocks are what ah ?

A: The easy wiring ; such as when installing the distribution cabinet , table lights or doors on every terminal count . Check line convenient ; easy to measure when a failure occurs tamper evident tapes . Node expansion ; same line number node expansion.

6 , how to choose the design of the substation transformer and terminal block ?

A: The transformer capacity to be calculated too big too small will not work ; terminal block for distance is generally not less than 350mm, the current loop must be current test terminal OT wiring .

Terminal blocks for easy wire connections and applications , it is actually some sealed inside an insulating plastic sheet metal , wire can be inserted into the hole at each end , for tightening or loosening screws , such as two wires , sometimes need to be connected , and sometimes you need to disconnect , this thing can use the terminal to connect them , and you can disconnect at any time , without having to weld them together or intertwined , it is quick and easy. And is suitable for a large number of interconnected wires in the power industry have a special terminal block tamper seal labels, terminal box , above all terminal blocks , single and double , current, voltage , ordinary, can be broken and so on. A crimp in order to ensure reliable contact with the area , and to ensure a sufficient current through .
