Terminal Blocks - Barrier Blocks

T38443-20-0 is a terminal block designed to separate low and dangerous voltages from each other. It provides a reliable and secure connection by joining two electrical circuits through isolated terminals, by eliminating arcing processes, and protecting personnel from high voltage electric shock.

Application Field

T38443-20-0 is primarily used as a connection for low or dangerous voltage electrical switchboards and installations, where there is the possibility of bumping or touching the terminals unintentionally. It helps to prevent electric shock or other hazards in high-voltage environments due to improper insulation or inferior workmanship.

T38443-20-0 also has a wide variety of applications in automotive and industrial electronics. It is widely used in motor control centers, electronic circuit boards, appliance control systems, LED lighting, emergency lighting systems, solar power systems, railway power converters, and various other control systems.

Working Principle

The T38443-20-0 terminal block is fitted with an insulation material between its two bars. This insulation is usually made of polyethylene and it creates a physical barrier between the connected circuits. This barrier prevents accidental shocks and arcing between these circuits.

When a connection is made, the top bar is connected to a terminal of one circuit and the bottom bar to a terminal of another. This completes the connection by closing a loop between the two circuits. The insulation material eliminates any arcing or other types electrical discharge that might occur due to a loose connection.

The T38443-20-0 terminal blocks are also fitted with a set of spring-loaded inserts. These inserts provide additional protection by ensuring that the bars remain firmly engaged even if the connection is accidentally pulled out. The spring-loaded inserts also reduce the risk of accidental shock by ensuring that the connection is made between the two conducting surfaces without any gaps.

The T38443-20-0 terminal blocks provide a secure connection between high and low-voltage circuits. This connection eliminates the risks of electric shock and arcing, and helps to protect personnel and equipment in industrial and automotive applications.
