Terminal Blocks – Headers, Plugs and Sockets: VM1555020000G Application Field and Working Principle Terminal blocks are important connection components in electrical engineering and come in various types including headers, plugs and sockets. In this article, we discuss the application field and working principle of one kind of header type terminal block, namely VM1555020000G. Application Field VM1555020000G terminal blocks are mainly designed for screw connection junction boxes or other types of electrical enclosures. Primarily, it is used in low-voltage installations and for applications that require the junction between stranded and rigid conductors. The terminal block has been proven to be reliable and suitable for low-voltage distribution, the connection of industrial machines or as control switch for household applications. The terminal block features 5 mm pins which can be crimped onto cables that are 0.14 - 2.5 mm² in size. Furthermore, the VM1555020000G has 5mm pitch spacing which can accommodate up to 40A of current, as well as reliable protective contact with screw connection and its renowned fast and simple assembly. The integrated capton tape can also be used in the cabinets to provide precise and organized wiring. Working Principle The VM1555020000G terminal block has 5 mm pitch spacing so each pin contact blocks on the front and rear side of each terminal has 5 mm maximum pin length as they are placed at holes of same size. The screwed block is fully compatible with internationally recognized standards and has an optical mechanical connection for the conductor connection. The unit is provided with pressure plungers and set screws located near the line contacts and secured against unintentional loosening by the pressure plunger. Tightness is achieved by a non-interchangeable ratchet mechanism that locks applied wires tightly. The terminal block also complies with the IEC 60947-7-1 standards and is made from superior grade, flame retardant materials which allow for trouble-free operation. The rear-side of the terminal block is made from carbon steel which can resist corrosion and ensure contact tightness. The contacts are machined from copper alloy which allows good electrical contact of both strands of conductors. The contact screw is tightened with the help of a keyed installation tool which works as an electrical contact toner to ensure electrical continuity between the contact and conductor strands. Conclusion The VM1555020000G terminal block is used in many applications due to its reliability and performance. The terminal block is ideal for low-voltage installations as it can accommodate up to 40A of current. Its 5 mm pins accommodate cables from 0.14 - 2.5 mm² in size, while its secure design and sophisticated ratchet mechanism ensure tightness and electrical continuity. The terminal block is made from superior grade, flame retardant materials which allow for trouble-free operation.
