## Summary description

The Wago 243-304 is a compact 4-conductor micro terminal block designed for secure electrical connections in junction boxes. Rated for 100 V, this grey terminal block provides reliable contact for solid conductors. It is an essential component for efficient and space-saving wiring in various electrical installations, ensuring stable performance and ease of use for professional electrical projects.

## Long description

The Wago 243-304 4-Conductor Micro Terminal Block is a professional-grade solution designed for secure and efficient electrical connections within junction boxes. Featuring the reliable PUSH WIRE connection technology, this compact component allows for quick and tool-free installation of solid conductors. Its grey, space-saving design is specifically engineered for applications where high-density wiring is required, ensuring stable electrical contact and long-term performance in various electrical installations.
Advantages
This terminal block offers significant benefits for electrical professionals, primarily through its compact size which maximizes space within crowded junction boxes. The PUSH WIRE technology facilitates rapid installation, reducing labor time while maintaining a high level of connection security. Its robust construction ensures that once a solid conductor is inserted, it remains firmly in place, providing a vibration-resistant and maintenance-free connection that meets stringent safety standards for electrical distribution.
Suitable for
Junction box wiring
Telecommunications and signal distribution
Low-voltage electrical installations
Building automation systems
Compact control cabinets
When it may not be suitable
This terminal block is designed specifically for solid conductors and is not suitable for use with stranded or flexible wires. It is also limited to low-voltage applications rated up to 100 V, meaning it should not be used in high-voltage power distribution circuits or industrial machinery requiring higher voltage ratings.
Key specifications
Connection type: PUSH WIRE
Number of connection points: 4
Rated voltage: 100 V
Conductor type: Solid conductors only
Compatible conductor diameters: 0.5 mm to 0.8 mm (24–20 AWG); 0.5 mm or 1 mm (24 or 18 AWG) for same-diameter applications
Color: Light grey
How to use
To use the Wago 243-304, ensure that the solid conductor is stripped to the appropriate length as specified by the installation requirements. Simply push the solid wire directly into the terminal entry point until it is fully seated. The internal spring mechanism automatically grips the conductor, creating a secure and reliable electrical connection. To remove a conductor, rotate it while pulling it out of the terminal block.
What to consider before purchase
Verify that your wiring consists exclusively of solid conductors.
Ensure the application voltage does not exceed the 100 V rating.
Check the conductor diameter to ensure compatibility with the terminal range.
Consider the number of conductors needed per connection point to ensure the 4-conductor capacity is sufficient for your project.
Usage recommendations
Always ensure that the power supply is disconnected before performing any electrical work. Use only compatible solid conductors to maintain the integrity of the PUSH WIRE connection and prevent potential contact failure.
