Product Model
UKH 95 BU
Key Features
- 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.
- 3Robust screw locking by means of spring-loaded elements in the clamping part.
- 4High voltage rating of 1000 V and maximum current rating of 232 A.
- 5Compatible with DIN rails (NS 35/15, NS 32) for easy mounting.
