## Long description

The LZ-B4/2 2-pole screw terminal block is a professional-grade electrical component designed to provide secure and reliable connections in various wiring applications.

The primary benefit of this terminal block is the inclusion of a wire protection washer, which significantly reduces the risk of wire damage or breakage during the tightening process. This feature ensures a consistent and firm contact between the terminal and the conductor, minimizing the potential for loose connections or overheating. The compact 2-pole design allows for efficient space utilization in junction boxes and control panels, while the high-quality materials used in its construction provide excellent electrical conductivity and resistance to environmental stress.

Use a compatible screwdriver to tighten the screw firmly until the wire is securely clamped. Verify the connection by gently pulling on the wire to ensure it does not slip out. Always ensure that the power supply is disconnected before performing any wiring work.
What to consider before purchase
Ensure the wire gauge is compatible with the terminal block capacity
Verify the total number of connections required for your specific project
Check if the installation environment requires a specific IP rating or enclosure
