A387308 is a type of terminal blocks, better known as barrier blocks. These blocks are essentials for wiring needs. Electrical components can be wired together through a barrier strip without having to splice each wire. This can make the process of wiring components much simpler and cleaner compared to splicing multiple wires. A387308 is particularly designed for harsh, demanding environments and can manage a wide range of power levels, from low level signal circuits to high voltage up to 600 VDC and 250 VAC.
Structure
A387308 barrier block consists of two pieces of aluminum die-castings, which are connected by a set of two screws. The upper aluminum die-casting has a grooved base with rectangular-shaped finger pieces extending from the base, and the lower aluminum die-casting is parallel to the upper die-casting and has two sets of brass contact strips embedded in it with steel spring contact pieces on the edges of the base. The two fingers pieces of the grooved base are connected to screws which when tightened firmly hold together the two pieces.Mounting
The terminal block is typically mounted onto a printed circuit board (PCB) or a housing, using an appropriate size mounting hole. The two mounting sectors can fit into even small mounting holes and can be tightened with two screws. The design of A387308 allows for multiple configurations of mounting.Application
A387308 is mainly used in power supply units, transistors, amplifiers, instrumentation panels, industrial controllers, telecommunication devices, medical devices, and high voltage power modules. It is also used in hazardous locations where shock, vibration, and moisture can be present.Working Principle
When the two halves of the terminal block are screwed together, the contact fingers form an electrical connection between the two aluminum die-casting pieces. This electrical connection allows for the passage of electrical signals and current flow. The contact fingers are corrosion-resistant and conductive which help in creating a strong electrical connection once the two halves are connected together.The contact strips of the flexible steel springs allow for an advantageous positioning of the terminal blocks according to the user’s needs. The steel springs ensure high electrical conductivity where each individual spring is connected to a contact point.Safety Features
A387308 offers a high degree of safety because of its design. Each part of the terminal block is tightly sealed which helps in protecting against dirt, dust, and contact with current-carrying surfaces. This makes it suitable for use in hazardous locations where shock, vibration, and moisture can be present. The two die-casting pieces are also protected by a sheet of plastic material which helps in providing insulation resistance. This insulation prevents shocks from being conducted through the contact fingers, thus ensuring safety.Conclusion
A387308 terminal blocks – barrier blocks are versatile and can provide a reliable electrical connection for a wide range of devices. They are also easy to install, eliminating the need to splice multiple wires for electrical wiring. In addition, these blocks are designed to provide a high degree of safety due to their tight seal, insulation resistance, and contact fingers. Therefore, A387308 terminal blocks – barrier blocks are a great solution for any wiring needs in high-voltage and hazardous environments.The specific data is subject to PDF, and the above content is for reference
