Terminal Blocks - Barrier Blocks

Barrier blocks are one of the many styles of terminal blocks available for electrical projects. They are widely used across multiple industries from automotive to general industrial equipment, due to their flexibility and reliability in a wide range of operating conditions. Their design utilizes a box-like plastic housing with several pairs of contact points, allowing positive and negative current entering the barrier block to be separated, and then distributed through an output side. This kind of terminal block is often referred to as a 0387201216.

General Design & Features

The 0387201216 is a single-wire connection device featuring two rows of contacts in a rectangular body. The contacts are arranged in two groups with four contacts each, spread along the length of the unit. This arrangement is ideal for applications where two voltages are required. The device offers electrical isolation between input and output voltages, as well as very low contact resistance and a low inductive connection. The exterior of the device is insulated in a rugged plastic housing, making it suitable for outdoor installations.

Applications & Operating Conditions

The 0387201216 is suitable for a wide range of both general and specific applications, from automotive and industrial to aerospace and energy applications. Most commonly, it is used to connect components in automotive wiring loom, air conditioning and lighting installations. It can also be used in circuits that require high voltage insulation and protection from short circuit events, such as in the case of medical equipment. Additionally, it is suitable for use in hazardous environments due to its UL and CSA Approval, and can handle voltage up to 400 volts.

Working Principle

The 0387201216 works by providing a positive and negative contact on each side of the block, separated by a barrier of insulation. These contacts ensure electrical isolation between the two ports. Power is routed into the input side of the block and routed to the corresponding output points via the connections on the output side. The voltage is isolated between the input and output so that the output voltage is the same as the input voltage. The output voltage can be adjusted using the screw on the side of the terminal block. The screw adjusts the tension on the outputs, which in turn controls the output voltage. Combined with the low contact resistance and low inductive connection, this makes the device very reliable in a wide range of operating conditions.

Conclusion

The 0387201216 is a versatile style of terminal block device designed to provide electrical isolation between two voltages. Its box-like plastic housing contains two rows of contact points and is suitable for outdoor installations. It is commonly used in automotive and industrial applications, and is also suitable for use in medical device applications. It can handle voltages up to 400 volts and is UL and CSA approved. It is highly reliable in a wide range of applications due to its low contact resistance and low inductive connection. Overall, the 0387201216 is a great choice for any electrical connection project.
