Terminal blocks are common in electrical engineering in combination wiring fixtures, according to the different needs of the project , the terminal block can achieve different digits installation. Due to different manufacturers , terminal models are not the same , but on the product itself, the basic unit can be used to represent bits , for example : 15P on behalf of the 15 terminals consisting of products.
Elinker Electric As a professional connector industry technical experts , providing a comprehensive range of terminal solutions for industry partners . Here Elinker Electric on the terminal block in the course of interpretation to analyze common problems , to provide you with the most scientific answer to the question .
1, what is the purpose of the grounding terminal block?
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 , what the circumstances of using the terminal block ?
A: The wire connections between different devices , you need to terminal blocks , some plug-in ( module ) also requires the terminal block.
3 , what 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 , What does the type of 4EN terminal block it mean ?
Answer : 4EN said contact area 4 mm2 .
5 , what are the common terminal blocks?
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 . 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 .
