RS PRO Earth Terminal Block, Screw Termination Earth terminal blocks let you safely ground/earth a current in a circuit, without the need to run a wire to the main ground/earth connection on a breaker or surge protector. These blocks are similar to regular terminal blocks, with a wire connection to the base of the block in order to ground/earth the circuit. These blocks are pluggable, which gives them a number of benefits over a screw system. They can be connected up and removed more quickly and easily, and they also allow for adjacent terminals of different sizes to be linked up. The terminals are designed to snap onto the TS 35 DIN rails. The terminal blocks are made from a PA6.6 polyamide material, which has been certified UL94-V2 for fire safety. Industrial circuit boards and control panels frequently make use of earth terminal blocks like these.
