Frequently Asked Questions
What is a Triple Level Push-in DIN Rail Terminal Block?
It is a high-density electrical connection block designed to mount on standard DIN rails. It features three stacked wiring levels, utilizing push-in spring connection technology for secure, tool-free wire termination.
What are the main advantages of push-in connection technology?
Push-in technology allows you to insert solid wires or stranded wires with ferrules directly into the terminal block without tools. This significantly reduces installation time and provides a reliable, vibration-proof, and maintenance-free connection.
Why are these terminal blocks offered in Grey, Blue, and Orange colors?
Color-coding is used to simplify circuit identification. Typically, Grey is used for standard phase/line connections, Blue is designated for neutral lines, and Orange is used for specific signal or warning circuits.
How does the triple-level design optimize cabinet space?
By stacking three independent electrical levels vertically within a single block, it allows you to connect three times as many wires in the same linear rail space compared to traditional single-level terminal blocks.
Are these terminal blocks compatible with standard 35mm DIN rails?
Yes, these terminal blocks are fully compatible with standard 35mm DIN rails (such as NS 35/7.5 and NS 35/15), ensuring seamless integration into existing control panels and distribution boards.
