Product Model
UKH 50 1500V BU

Selling Points
- 1Reliable cable connection ensured by three-point centering of the conductor in the prismatic sleeve base.
- 2Low contact resistance due to ribbing on the contact surface.
- 3Screw locking by means of spring-loaded elements in the clamping part for secure connections.
- 4Rated surge voltage of 8 kV and overvoltage category III for enhanced safety.
- 5Compatible with various mounting types including NS 35/15, NS 32, and NS 35/7,5 for versatile installation options.
