Terminal Blocks - Accessories encompass a wide variety of solutions to serve many applications. Among these, the 268A model is a versatile type of terminal block that uses screw-type connections for power networks and circuits. 268A157-3 is a recent iteration of these terminal block solutions designed to offer greater flexibility, reliability, and safety in AC & DC power networks and circuits. In this article, we discuss the 268A157-3 terminal block’s applications and working principle.

Application of 268A157-3 Terminal Block

The 268A157-3 terminals offer increased reliability and performance in power systems. They are well suited to a variety of industry applications, from residential, commercial, and industrial to telecommunications, transportation, and aerospace. Some of the most common applications include:

• Low-voltage and medium-voltage circuit breakers
• Control panels and motor controls
• Mobile power systems and home automation systems
• Network and system integration
• Signaling and security systems
• Medical equipment and instrumentation

The 268A157-3 terminal blocks offer improved safety, performance, and ease of installation. They are designed to be mechanically robust and work reliably under high levels of vibration. Additionally, their surface-mount configuration eliminates the need for wiring trays and can fit into tight spaces, making them suitable for mounting in existing equipment.

Working Principle of 268A157-3 Terminal Block

268A157-3 terminal blocks feature a patented ‘Gas-Tight’ technology that provides superior connection and safety. This improved design offers tight contact between the screw and the terminal block’s contact surfaces. The enhanced connection creates a gas-tight enclosure that prevents air and moisture from getting inside the blocks. This helps protect against corrosion and terminal contact oxidation, ensuring a reliable connection over time.

The 268A157-3 terminals also incorporate the patented ‘Snap-Lok’ technology. This feature integrates two metal clips into the terminals that are designed to firmly hold the cables in place. The Snap-Lok technology allows the cables to be easily inserted and removed from the terminals and provides superior reliability under vibration conditions.

The 268A157-3 terminal blocks also incorporate a dual-action contact design. This is a unique feature that allows the terminals to grip the cable securely and provide redundant contact on the two opposing sides of the terminal. This helps improve signal integrity and reliability.

Conclusion

The 268A157-3 terminal blocks offer superior reliability, safety, and performance in AC & DC power systems. Their unique features make them well suited to a variety of industry applications, including low-voltage and medium-voltage circuit breakers, mobile power systems, network and system integration, and signaling and security systems. The 268A157-3 terminals feature patented ‘Gas-Tight’ and ‘Snap-Lok’ technologies, as well as a dual-action contact design to provide reliable contact even in harsh vibration conditions.
