Terminal Blocks - Barrier Blocks

The SEFX-1 is a terminal block for controlling current within an internal circuit and is part of an entire family of terminal blocks that possess one of the most powerful functions in the industry. The SEFX-1, as part of that family, is a barrier block for voltage and current applications but differs in function from its other family members.

The SEFX-1 has a specialized circuit design that allows a single connection between two voltage cables to be accomplished safely and without the need for multiple connections. This single connection allows the current and voltage to traverse in opposite directions throughout the circuit; thus allowing the control of the power supply from a single power grid. The SEFX-1 can be used in both domestic and commercial applications.

The SEFX-1 utilises a few key components in order to achieve the safe connection of two opposing power sources. Firstly, there are two contacts that run the length of the terminal block; each contact is encoded with specific numbers and symbols which serve a vital purpose in the functionality of the unit. Each contact also incorporates two additional components, the ‘barrier’, which separates the two contacts and ‘insulators’ which play a key role in ensuring that the current running between the two contacts never overpowers the insulation protection.

The insulators are crucial as they provide insulation from the power source to the other end of the contact and also regulate the current that can pass through. The ‘barrier’ helps to separate the two contacts and provides a reliable mechanism of controlling power output in high voltage systems. The two insulators and the ‘barrier’ will always be found on the same side of the block, and always against the point at which the power enters the terminal block.

The key benefits of using the SEFX-1 terminal block in a commercial system are the safety, reliability and overall cost savings. The reliable circuit design aids in preventing over abundant current and voltage traveling through the circuit and further assists in safe power control. Further, the ability to not have multiple terminals and contacts shared between opposing power sources also helps reduce costs.

The SEFX-1 is effective as it enables the user to control the flow of current between two opposing voltage sources with a single connection. This ultimately decreases the cost of energy consumption as the power can be distributed safely without the need for an additional connection. The ability to apply the SEFX-1 in various commercial and domestic applications makes the device adaptable across industries.
