Product Model
UKH 70-3L/N
Key Features
- 1High Load Capacity: Handles up to 192A with a 70 mm² conductor cross section.
- 2Durable Construction: Ensured by three-point centering of the conductor in the prismatic sleeve base.
- 3Low Contact Resistance: Achieved due to ribbing on the contact surface.
- 4Secure Connection: Screw locking by means of spring-loaded elements in the clamping part.
- 5Versatile Mounting Options: Compatible with NS 35/7,5, NS 35/15, NS 35/15-2,3, and NS 32 mounting types.
