PRK terminal blocks with Push-in connections feature optimisations that existing systems do not have.  Despite the high contact force of the Push-in spring, the CONTA-CLIP solution enables solid wires, as well as stranded wires with wire-end ferrules, to be safely terminated using less insertion force.  Opening the clamp to release the wire is done by using the insulated integrated pusher, ensuring the clamping point can be pressed and is touch-safe. This provides a noticeable time advantage during the wiring process.
