DIN Rail Terminal Block

DIN rail terminal blocks are used to protect electrical circuitry from long-term damage and failure due to overcurrent and short-circuiting. DIN rail terminal blocks clip onto DIN rails, which are standard-sized metal rails found in control cabinets.

DIN rail terminal blocks are made of plastic, thus insulating the electric current running through them.

What is a DIN rail terminal block used for?

DIN rail terminal blocks are typically used to secure two or more wires together. In some cases, DIN rail terminal blocks are used to terminate wires. Both fused and non-fused DIN rail terminal blocks are available, with fused blocks used more widely due to the added protection they offer. DIN rail terminal blocks are also often used to connect wires to another circuit or device.

How many wires can you put in a DIN rail terminal block?

The number of wires you can put into a DIN rail terminal block depends on its size. When looking for a DIN rail terminal block, look for multiple wire blocks that highlight how many wires you can use.

What is a DIN rail switch?

DIN rail switches are used to connect electrical devices in working in extreme operating conditions, and that need to withstand shocks and vibrations. DIN rail switches can commonly work in temperatures from -40°C to 75°C.

Are all DIN rails the same size?

No; several sizes of DIN rails are available. The biggest DIN rails in terms of length are two metres long, with one metre versions also available. DIN rails are available in widths of 35mm, 32mm, and 15mm, with depths of 7.5mm and 15mm.
