Product Model
UKH 150 BU
Selling Points
- 1Reliable cable connection ensured by three-point centering of the conductor in the prismatic sleeve base.
- 2Low contact resistance of the contact surface due to ribbing.
- 3Screw locking by means of spring-loaded elements in the clamping part.
- 4Maximum load current: 309 A with a 150 mm² conductor cross section.
- 5Insulating material group I and overvoltage category III for enhanced safety.
