Terminal Blocks - Barrier Blocks

0387890069 is a type of terminal block or barrier block designed specifically for protecting circuits against overvoltage by creating an isolated boundary between systems. It is designed with two terminals – the primary and the secondary. The primary terminal is connected to the main circuit, while the secondary terminal is connected to a short circuit that only becomes active when the voltage exceeds a certain value. The block is composed of a dielectric material surrounded by metal plates. When a voltage exceed is detected, the dielectric separates from the plates, thus creating an isolated section that prevents a short circuit.

Application Field

0387890069 is mainly used in surge protection applications, where the high voltage events are unpredictable and could affect sensitive electronic equipment installed in the system. In industrial sectors, such as oil drilling machines, wind turbines, and electric locomotives, these blocks are critical in protecting the equipment from the probable voltage surges. Moreover, they are becoming increasingly popular in the automotive industry. With the introduction of features such as Automatic Electronic Braking System (ABS), Electronic Stability Program (ESP) and All Wheel Drive Systems (AWD), these blocks play an important role in ensuring that all the added electronics do not get damaged due to high voltage stresses.

Working principle

The basic functionality of 0387890069 is simple. Once the connected system detects a voltage exceed, it initiates the operation of the block. As the voltage spikes, it triggers the release of an external nitrogen gas stored in a compressed state within the block. This gas expands and creates a dielectric chamber that separates the primary and secondary terminals. Any excessive voltage is then contained in the dielectric chamber and dissipated via an internal resistor. This prevents the short-circuit of the primary terminal, ensuring the safety of the system.

The value of the resistor specifies the energy a block can absorb, which affects the dissipation time of the voltage. The material used for the resistor also has a significant impact on the performance of the block, since different materials have different resistive properties. To put it simply, material with higher resistivity dissipates a higher voltage more quickly.

Conclusion

0387890069 is based on simple yet effective technology that helps prevent overvoltage in circuits. The design of its dielectric chamber and the use of an external nitrogen gas provide an efficient mechanism for the block to absorb any excess voltage without damaging the system’s sensitive components. Overall, it is an essential part of protecting electronic equipment from voltage spikes.
