UKH 50-IB BU - High-current terminal block
High-current terminal block, with Allen screws, nom. voltage: 1000 V, nominal current: 150 A, number of connections: 2, number of positions: 1, connection method: Screw connection, cross section: 16 mm2 - 70 mm2, mounting type: NS 35/7,5, NS 35/15, NS 32, NS 35/15-2,3, color: blue
- Reliable cable connection is ensured by three-point centering of the conductor in the prismatic sleeve base
- Low contact resistance of the contact surface due to ribbing
- Screw locking by means of spring-loaded elements in the clamping part
