QUICK-CONNECT by Bals is a screwless connection technology based on the spring-clamp principle.



Overview of the advantages

  • QUICK-CONNECT is available from 16A 3-pole to 63A 5-pole
  • Screwless connection technology, time savings of up to 70%
  • Faster, more reliable and controlled conductor connection
  • The terminal accepts all types of copper conductors
  • QUICK-CONNECT is maintenance-free, insensitive to shocks, vibrations and temperature fluctuations
  • Colour-coded conductor entry for reliable installation





Fast, faster, QUICK-CONNECT: with the introduction of this screwless connection technology in 1998, Bals again set new standards. We were the first company to offer this reliable and timesaving innovation. The patented system, which has unbeatable advantages over previously used screw connections, quickly developed into the industry standard.
As the only manufacturer worldwide, it goes without saying that Bals offers a screwless terminal connection for plugs and sockets even for an amperage of 63A. Also truly unique are the 16A and 32A QUICK-CONNECT phaseinverters.

In the opinion of many experts, our QUICK-CONNECT concept, which is based on the screwless spring-clamp system, is the best-suited system for quickly and easily meeting the various challenges encountered in the wiring and maintenance of industrial plugs and sockets in a controlled manner. 



  • The terminal accepts all types of copper conductors, rigid or flexible, with or without wire end ferrule as well as conductors of all quality grades irrespective of the conductor diameter or conductor insulation.
  • On delivery, the terminals are open and the contact pressure of the springs is optimally set.
  • Pressing the contact slide or locking lever with a finger visibly, audibly, reliably and permanently closes the terminal after the stripped conductor has been inserted.
  • Rewiring is no problem. Pressing the locking lever or contact slide again releases the conductor; unlinke insulation displacement connector technology, the conductor can then be used again without needing further processing steps.
  • The damage-free conductor clamping guarantuees an optimum connection over the entire service life.
  • QUICK-CONNECT is maintenance-free, insensitive to shocks, vibrations and temperature fluctuations.
