Description

The Weidmuller WDU 2,5 is a grey screw connection feed-through terminal block for 2.5 mm2 conductors, part of the W-Series DIN rail terminal system. The block uses a steel clamping yoke with a screw that closes onto the conductor, giving a vibration resistant connection without special tools. Blocks are rated 800 V and 24 A and accept solid conductors from 0.5 mm2 to 4 mm2 and flexible conductors from 0.5 mm2 to 2.5 mm2. Accessories include end covers, partition plates, marker holders, jumper bars and cross-connection combs.
