Terminal Blocks - Barrier Blocks

The 432200-20-0 terminal block and barrier block are primarily used in control and electrical power distribution. These products are attractive due to their easy installation; the ability to provide maximum current; and vibration resistance.

Application Field

The 432200-20-0 is primarily used in control and electrical power distribution, and used for a variety of electrical applications, such as monitoring and controlling industrial and commercial equipment. It is an excellent choice for use in networks where a small form factor is desired. Because it is a barrier type, it is ideal for use in industrial and electrical distribution setups where it is desirable to keep one side of equipment isolated from the other.

It is also used in high-voltage applications, such as in the field of automotive, telecommunications, and power electronics, since the bars dead front design and raw brass plated construction provides an excellent barrier between the two power busses. It can also help to reduce the incidence of electrical fires due to its ability to keep two sides of the system isolated.

Working Principle

The 432200-20-0 consists of two perforated barrier blocks. The connection between the busses is done by inserting a terminal pin between the two blocks and securing it with a screw. This acts as a physical barrier, and keeps the units electrically isolated, as the screw head acts as a conductor to one side, and its shaft as a conductor to the other.

The unit is designed to resist vibration and shock. In addition, it is designed to with stand up to 461 A continuous current per pin, and a UL listed terminal block is available to ensure compliance with a variety of safety regulations.

The working voltage of the 432200-20-0 is 450VAC/DC maximum, with a current rating of 50AMP (max). The unit is available in either a 4 or 6 post arrangement, and a variety of colors are available for ease of identification.
