Fused Terminal Blocks

In electrical control cabinets, fused terminal blocks collect, organise and distribute signals with a higher degree of protection than non-fused terminal blocks. This is because they allow electricity to flow through a fuse. If the currents passing through are greater than the fuse amp, the fuse will blow, protecting the device from excess current. 


What are fused terminal blocks used for?

Widely used in industry, fused terminal blocks protect equipment from overcurrent and prevent electrical fires. Fused terminal blocks can integrate with any circuits you're wiring, creating a durable and safe connection for any electric power system. If the maximum current needs to be increased then you can simply replace the fuse within the terminal block with a higher amp.


Types of fused terminal blocks

Fused terminal blocks are available in different mount types such as screw down or DIN rail mount, for use when  your circuit breakers have been mounted with a metal rail. They're constructed in a range of compact sizes to help save panel space. Fused terminal blocks are available with different fuse-size inserts. The size you choose will depend on the circuits you're connecting.
