0399310421 Application Field and Working Principle

The 0399310421 terminal block is part of the Harris 203 Series, a range of customer-orientated connectors that are designed to perform in all connection and disconnection operations. The series features disconnect-through-hole technology that eliminates shorts and exposed contacts during disconnection, providing reliable connection and safety.

The 0399310421 terminal block operates within a voltage range of 2.5 - 40V, providing reliable connection throughout the operating voltage range. It has a current rating of up to 11A and can be used in applications with up to AWG 14 wire size. The terminal block is designed for easy installation, featuring solderless spring-clamp technology that speeds up installation times and reduces labour costs.

The 0399310421 terminal block is designed with standard 5.08 (TRD1) terminals that are compatible with most existing connectors. It also has an optional built-in diode for controlling voltage transients and can accommodate up to 40kA interrupting capacity. Additionally, the terminal block has a pre-terminated termination system that reduces wiring complexity and shortens installation times.

Operation

The 0399310421 terminal block operates to provide electrical connection between two or more conductors. It is a two-piece terminal block that is inserted into housing for simple installation and operation. The housing includes two slots for easy connection of stranded or solid copper wires. It has a spring-clamp contact system that permanently and securely holds the two wires in place and provides a secure connection that can handle a wide range of current.

Once the two wires are inserted into the slots, the clamp is tightened so that the wires are securely held in place. This provides an electrical connection between the two conductors. The terminal block also features a built-in tension indicator that shows whether the connection is secure. The indicator operates by changing color when the tension is sufficient, providing a visual cue that the connection is secure.

Advantages

The 0399310421 terminal block has a number of advantages, including:

• Reliable connection and safety
• Compatibility with existing connectors
• Reduced wiring complexity
• Simple installation
• Wide range of current
• Built-in tension indicator

Conclusion

The 0399310421 terminal block is a reliable and safe connection that can accommodate a wide range of current and is compatible with most existing connectors. It features a simple installation process and built-in tension indicator that shows when the connection is secure. Additionally, it has a pre-terminated termination system that reduces wiring complexity and shortens installation times.
