Three phase four wire connection terminal block for metering box
Application of this terminal block enables house service wire to be separated from meter service wire, which solves the problem of parallel connection. Terminal block cover can be sealed to prevent electricity theft ; Neutral line terminal block can be earthed repeatedly. It is in conformity with the“special, sealed”principle standardization of one-household one-meter. The products are applied in“one-household one-meter”electric energy metering box.
This series of terminal block adopt high-molecular polycarbonate material imported from America. It has advantages of high impact resistance, moisture resistance, favorable insulation; ageing resistance, flame retardant, high temperature resistant, etc..The binding screw adopts compound recess , which is suitable for flathead screwdriver and crossed screwdriver The products are popular due to compact volume, large capacity, high withstand voltage, reasonable structure, and elegant appearance.
