UKH 50-F BU - High-current terminal block

High-current terminal block, nom. voltage: 1000 V, nominal current: 150 A, number of connections: 2, number of positions: 1, connection method: Screw connection, Rated cross section: 50 mm2, cross section: 16 mm2 - 70 mm2, mounting type: direct screw connection, color: blue

  • Reliable cable connection is ensured by three-point centering of the conductor in the prismatic sleeve base
  • Screw locking by means of spring-loaded elements in the clamping part
  • Low contact resistance of the contact surface due to ribbing
