3 Pin 5mm Pitch Plug-in Screw Terminal Block Connector is a type of electrical connector, frequently used to connect wires to the PCB. The connector has a screw in each pin to fasten the wire securely. It has tin-plated brass for pin header and has nickel-plated brass contacts. However, the screw terminal blocks could provide 16A/300V nominal rating for the DC current. The Dielectric strength is more than 2kV.

Other than this, it could provide more than 1000 M ohm Insulation Resistance in 500 VDC. The connector is made using PBT (Polybutylene terephthalate) which is mechanically strong, heat resistant(UL94-V0 or V2) and has good insulation properties.
