The tightening and un-tightening operations are extremely simple and they can carried out with tools, such screwdrivers, which are always hand. Its however important use appropriately sized screwdriver order avoid the damaging either the screw itself the insulating body. tightening reliability: special orthogonal grooves the bottom the conducting body and the lower surface the pressure plates, ensure under all conditions the perfect electrical contact with the conductors and efficient mechanical clamp. ounting: CBD series polyamide terminal blocks are designed mounted two types rail, “G32” (acc. The tightening process means screws ensures the best mechanical performance and efficiency the current flow.

type connection: means screws, both sides, indirect and anti-loosening. other functions: besides their main feed-through function, CBD terminal blocks are designed such way carry out other functions. fact, means prearranged threaded hole the upper side the conducting body possible: create cross-connection (either permanent switchable) between two adjoining terminal blocks create multiple common bar connection between several adjoining terminal blocks insert socket for test plug insert composable test plug for multiple signal shunting. conducting body: the tube type entirely copper and zinc alloy and treated ith nickelplating; the characteristics the material used and the manufacturing methods are such avoid the phenomenon “seasoning cracking”. suitable for the connection, with without preparation conductors all cross-sections. The grip made particularly effective the spring function the pressure plate, which certain way and under the pushing action the screws, tends flex; this way reaction the head the screw itself, exerted, resisting unscrewing, even under dynamic stress (vibrations). The depth into which the conductor can inserted limited partition the insulating body. ease insertion: insertion the conductor into the terminal block made easy by: sloping entrance planes the insulating body the rounded edges the pressure plate appropriately sized entrance hole, with reference the diameter the maximum permitted conductor. The tightening screws are accessible only with adequate screwdriver and the particular shape the screws makes impossible lose them
