Invalid input
  • Protected against mismating and maintenance-free
  • Push-in CAGE CLAMP® spring pressure connection technology allows solid conductors to be simply pushed into a unit
  • Compact design with 4.4 mm pole spacing
  • Components can be clearly printed on and color-coded to meet custom requirements
  • When assembled, the installation connectors complies with IP40 and are suitable for easily accessible areas

All connectors for mounted installations (snap-in versions for lighting fixtures or devices, all types of PCB and distribution connectors) are factory-equipped with locking levers to ensure plugs and sockets are securely locked. Additional locking levers are only required for flying leads (plug/socket).
Note on mismating protection:
All WINSTA® components are 100% protected against mismating when:
a.) plugging different numbers of poles
b.) plugging while rotated 180 

c.) plugging while laterally staggered
d.) plugging one pole

Safety information 1:
Application note for the U.S. market (USR): Some versions may also be used for current interruption in accordance with the UL certificate in select applications with currents below 5 A and voltages up to 600 V. For further information, please contact your local sales office.
