Frequently Asked Questions
Q
What are Screw Connection DIN Rail Terminal Blocks?
Screw Connection DIN Rail Terminal Blocks are modular, insulated blocks used to secure and connect two or more wires together safely within electrical panels and industrial control systems, designed to be mounted on standard DIN rails.
Q
Why are there different colors for these terminal blocks?
Different colors help electrical engineers and technicians quickly identify wiring functions. For example, green or yellow is typically used for grounding (PE), blue for neutral (N), and grey, black, or red for phase/live lines.
Q
What type of wire is compatible with screw clamp terminal blocks?
They are compatible with both solid and stranded copper wires. For stranded wires, using wire ferrules is recommended to ensure a secure, reliable connection and prevent individual strands from fraying.
Q
Are these terminal blocks compatible with standard 35mm DIN rails?
Yes, these terminal blocks are designed with a universal mounting foot that easily snaps onto standard 35mm DIN rails (both top-hat and G-type rails, depending on the specific model specifications).
Q
What are the main advantages of screw connection technology?
Screw connections provide high contact force, low voltage drop, maintenance-free reliability, and the ability to connect multiple wire sizes in a single block, making them the most widely accepted termination method globally.
