MKKDS 3/ 8-5,08 - PCB terminal block

PCB terminal block, nominal current: 22 A, rated voltage (III/2): 400 V, nominal cross section: 2.5 mm2, number of rows: 2, number of positions per row: 8, product range: MKKDS 3, pitch: 5.08 mm, connection method: Screw connection with tension sleeve, screw head form: L Slotted, mounting: Wave soldering, conductor/PCB connection direction: 0 °, color: green, Pin layout: Linear pinning, Solder pin [P]: 5 mm, number of solder pins per potential: 1, type of packaging: packed in cardboard. The article can be aligned to create different nos. of positions!

  • Well-known connection principle allows worldwide use
  • Low temperature rise, thanks to maximum contact force
  • Allows connection of two conductors
  • Conductor connection on several levels enables higher contact density
  • Integrated protective guide prevents incorrect insertion of the conductor underneath the tension sleeve
  • The latching on the side enables various numbers of positions to be combined
