Contact SupplierPhoenix Contact screw terminal blocks are designed for very high demands. An important characteristic is the maintenance-free connection of conductors. It is not necessary to tighten the terminal screws. The screws are prevented from loosening by the “Reakdyn principle", a screw locking technique developed by Phoenix Contact.
All kinds of copper conductors can be clamped without pre-treatment. Splicing protection can also be used in the form of ferrules. A special characteristic of the screw clamping body is the multi-conductor connection, which is often necessary. Very large conductor cross sections up to 240 mm² can also be wired gas-tight and with long-term stability thanks to the high contact forces.
