Fixed terminal block
What is a terminal block?
Because its English name is "Terminal block", it is sometimes also called a connection terminal.
It is commonly used as a cable connection and relay component in switchboards and electrical equipment.
Mounting holes on both sides of the body allow screw fixing for organized wiring.
Numbers printed on the transparent cover make wiring management easier.
How to use the fixed terminal block
When multiple cables need to be connected, a fixed terminal block provides relay points that make each cable connection easy to identify.
When relocating a distribution board, the terminal block helps simplify reconnection at the new location.
If a switchboard fault occurs, each terminal block can be inspected individually to help identify the cause.
Material characteristics
The body and cover are made of polycarbonate (PC), the conductive plate is nickel-plated brass, and the terminal screws are made of iron.
The UL94V-2 (UL94V-0) flame-retardant rating indicates that the material extinguishes within 10 seconds in a vertical flame test, supporting safer use.
Each terminal block uses M3 mounting screws and is available in 3-, 4-, 6-, and 12-pole specifications for different wiring requirements.
