Terminal Blocks - Barrier Blocks

A barrier block, or terminal block, is an electronic device that can provide electrical insulation between two conductors. Barrier blocks can also act as junction points between two or more wiring systems. Commonly used in automation and signal processing applications, a barrier block is characterized by a two-piece enclosure with two sides: a barrier side and a contact side. The barrier sides contain system terminals or connectors that accept and secure wires to the cable, and the contact side contains contacts or screw terminals that securely attach a wire to the barrier block conductor.

The model number 325101-20-0 is a terminal block from manufacturer Tri-Star that features a mounting design that is US UL94 V-2 approved. It is a 20-amp rated single-pole barrier block. It has a rated earth leakage current of 0.5 amps and a rated insulation voltage of 1500V AC. The terminal block features a terminal connection rating of 0.1-25A, and a rated working voltage of 250V AC or 24V DC. The block is suitable for use in a variety of applications, including control systems, instrumentation, and automotive.

Application Field

The 325101-20-0 terminal block is designed for use in a wide variety of applications. It can be used in control systems to provide a convenient connection point for a number of wires. It is also well-suited for use in instrumentation projects, where it can provide an easy way to quickly connect multiple wires. The block is also ideal for automotive applications, such as wiring harnesses, where its small size and reliable connection make it ideal. In addition, the 325101-20-0 is also an excellent choice for providing reliable electrical insulation in any high-voltage or current application.

Working Principle

The working principle of the 325101-20-0 terminal block is based on providing reliable electrical insulation and a secure connection for the wires. The block has a two-piece enclosure, with two sides: a barrier side and a contact side. The barrier side contains system terminals or connectors that accept and secure wires to the cable, while the contact side contains contacts or screw terminals that securely attach a wire to the block\'s conductor.

The model numbers of the terminals within the block indicate the rated current and voltage of the complete terminal. For the 325101-20-0 terminal block, the number indicates it has a rating of 0.1-25A and rated working voltage of 250V AC or 24V DC. Furthermore, the terminals have a rated earth leakage current rating of 0.5A and a rated insulation voltage of 1,500V AC. This ensures that the block will safely and reliably provide electrical insulation and a secure connection for the attached wiring.
