JS terminal block


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
