Frequently Asked Questions
What is a Triple Level Push-in DIN Rail Terminal Block?
It is a high-density wiring solution designed to connect three independent electrical circuits vertically on a single DIN rail slot, significantly saving installation space inside control cabinets.
What are the benefits of using push-in spring connection technology?
Push-in spring technology allows for fast, tool-free installation of solid wires or stranded wires with ferrules. It ensures a secure, vibration-proof, and maintenance-free connection, reducing wiring time by up to 50% compared to traditional screw terminals.
Why are there different colors (Grey, Blue, Orange) for the terminal blocks?
Color coding is utilized for quick circuit identification. Generally, grey is used for standard phase/feed-through wiring, blue indicates neutral conductors, and orange is often used for specific signal paths or warning circuits.
Are these terminal blocks vibration-resistant?
Yes, the integrated spring mechanism provides continuous, gas-tight pressure on the inserted conductor, preventing loose wiring caused by vibrations or temperature fluctuations.
Are these products compatible with standard mounting rails?
Absolutely. They are designed to fit standard 35mm DIN rails (NS 35/7.5 and NS 35/15), ensuring universal compatibility with existing industrial cabinets.
