The product family comprises terminal blocks that are based on a spring clamp connection. By spring clamp connection, we mean an electrical connection which is established by clamping an individual stripped conductor by means of a spring. It is suitable for solid wires and multi-stranded wires with a nominal cross section of 0.08 - 2.5 mm2 and permits - direct clamping without preconditioning of the conductor - direct clamping with splice protection - indirect clamping via an end sleeve or pin cable lug
The pluggable terminals are fastened to the PCB via matching multi-pin connectors. Since the terminals are not firmly fixed on the PCB but plugged onto multi-pin connectors, they are called pluggable terminals.
