Barrier blocks are an integral piece of hardware in electrical systems. These housing blocks are designed to create a barrier between the conductor and the electricity-controlled components, such as motors, switches, etc. By doing so, they are capable of preventing dangerous fault currents and short circuits.

One of the most commonly used barrier blocks is the CFTD-17. It is a product of the ABB group, and its application fields include both commercial and industrial power systems. The CFTD-17 is a modular safety barrier system that provides reliable protection against short circuit current flow, as well as isolating power to various electrical components.

The CFTD-17 is composed of a variety of parts, including the barrier block itself, the connecting cables, the terminals, the contact springs and the finger guards. All these components must be installed correctly so that the CFTD-17 can operate correctly. The barrier block is designed to accept up to two cables, which can be connected in parallel to ensure continuous power supply. The terminals and the contact springs are also necessary when installing the CFTD-17 in order to ensure a correct connection.

The actual working principle of the CFTD-17 is quite simple. The barrier block can be installed between the incoming power source and the electrical components that require the power supply. In the event of a short circuit, the current flowing through the barrier block will be reduced by the increased resistance. This increased resistance will help prevent the current from reaching the protected components, thus mitigating the risk of damage or fire.

The CFTD-17 is a vital piece of safety hardware and should never be overlooked when installing electrical components. It has been designed to provide reliable protection against short circuit current flow and is capable of isolating power to various electrical components. It is strongly recommended that the CFTD-17 is installed correctly and maintained regularly in order to ensure the safety of personnel and equipment.
