Nikki Fixed Terminal Block
Manufacturer: Nikki Co., Ltd.
What is a fixed terminal block?
Technicians often call it a terminal block, using it to connect and relay cables to electrical devices like breakers in control panels.
The mounting holes on both ends of the unit allow you to fix the screws, which helps organize the wiring. In addition, the transparent cover has numbers printed on it, which makes it easy to manage the wiring.
How to use fixed terminal blocks
When connecting multiple cables, technicians use fixed terminal blocks to clearly identify connections. Terminal blocks also simplify reconnections when relocating control panels and help isolate issues for easier troubleshooting.
Material
The body and cover use polycarbonate, the conductive plate uses nickel-plated brass, and the terminal screws use iron. It meets UL94V-2 (or V-0) flame retardant standards and resists ignition under a 10-second vertical gas flame. Mounting options include M3 and M4 screws, with 3, 4, 6, or 12 poles—choose based on your application.
