A-TB750-VJ21V Application Field and Working Principle

Terminal Blocks - Wire to BoardTerminal blocks are among the most popular connective accessories used in commercial, industrial and automotive electrical circuits. The A-TB750-VJ21V terminal block is an industry standard type that is used as adjustable jumpers between two electric currents. It serves to replace the traditional rotary wiring usually found in junction boxes and distribution boards. The device provides an efficient way of changing or interrupting the electric current without the need of a specialized technician.The A-TB750-VJ 21V terminal block is an 8-pole wire-to-board connector with a pitch of 8.2 mm and a height of 15 mm. It is capable of accommodating disilicon or tinsulfere insulated wires with a size ranging from 12 AWG to 22 AWG. This device’s low voltage rating of 250 volts makes it suitable for applications involving moderate current ratings such as 120 VAC single phase or 208/220/240 VAC single phase. Termination of the device is made through a screw type terminal, requiring no extra tools and ensuring secure connections without the possibility for loss of contact under extreme vibration.The A-TB750-VJ 21V is constructed from UL 94V-0 rated materials and features anti-humidity properties, allowing for it to be submerged to up to 120 meter of depth. The coupling is done through an ejector system. To couple the junction block, a tab on the bottom part of the male housing. This allows the female housing’s anti-rotation mechanism to actuate and fix it while inserting.The contact system employed by the A-TB750-VJ 21V is a screw type terminal, made of bronze-plated phosphor-bronze and having a contact resistance of 6 mOhm maximum. Maximum current ratings can support up to 15 A and the device has a maximum operating temperature of 85°C. Additionally, it has UL recognized and CE certified marking, offering a further guarantee of its quality and safety.The A-TB750-VJ 21V is a very versatile device. Its easy to install and safe termination method is suitable for use when used for applications that range from low to high power. It is also well suited for use in various environments, including outdoor,tough, wet and corrosive environments. The device is correctly sized to fit into and out of various junction boxes while still supporting its contact rating and ensuring a safe connection.The versatility of the A-TB750-VJ 21V terminal block is enhanced by the fact that it does not require specialized technicians to install it. This makes it a very attractive option for applications that require frequent changes of the circuit or need to be quickly installed or modified. Furthermore, the device’s wiring is small enough for most enclosures and wiring systems, reducing the need to make costly accommodations to their existing electrical systems.The A-TB750-VJ 21V terminal Block is specifically designed to be a safe and cost-effective way to manage and connect both low and high-power circuits. It has a wide working temperature range, enabling it to maintain a reliable connection even in hostile environments. Its screw terminal type contact system allows for tight and secure connections without the need for specialized tools. Overall, this makes the device well suited for a wide range of wiring and various industrial or commercial applications.
