The selection of terminal blocks has always been a hot topic! There are only some product parameters or even no parameters to buy. It is a headache to buy terminal blocks. Let's take a look, how can we choose?
First of all, before choosing a type, you need to know what kind of terminal block you want.
According to the functions of the terminals: ordinary terminals, safety terminals, test terminals, grounding terminals, double-layer terminals, double-layer terminals, three-layer terminals, one-input-two-outlet terminals, one-input-three-outlet terminals, double-input-two-outlet terminals, circuit breaker terminals, overvoltage protection terminals, sign terminals, etc.
Classified by current: small current terminals, high current terminals, etc. According to its appearance, it can be divided into rail terminals, fixed terminals, PCB terminals, etc.
Then when choosing, mainly consider the following points:
①Whether the wire to be connected is hard or soft
② What is the cross-sectional area of the wire in square millimeters?
③ How much current and voltage do the terminals need to withstand
④Multiple connectors should be selected, if you need to connect several wires together, use a connector with several holes
