What is a junction block?
DIN rail junction blocks are mainly used to protect electrical systems from overcurrents and short circuits. Made of plastic material, these terminals isolate the electrical current that passes through them, guaranteeing effective protection.
DIN rail versions with fuses often include a hinged section to accommodate the fuse, allowing for easy power interruption.
Terminal blocks, with or without fuses, can be used in various contexts, such as:
- Energy management
- Power supplies
- Lighting controllers
- Building management systems
How are junction blocks installed?
The terminal blocks are simply attached to a standard metal DIN rail in control cabinets or electrical panels. The electrical wires are easily fixed in the terminal block cages, available in screw or spring versions. The size of the cable section must be adapted to that of the terminals, in accordance with the current intensity.
