Product Model
UKH 150-F
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 for efficient power transfer.
- 3Screw locking by means of spring-loaded elements in the clamping part for secure connections.
- 4Insulating material group I and overvoltage category III for enhanced safety and reliability.
- 5Maximum load current of 309 A with a conductor cross section of 150 mm² for high-current applications.
