1020000000 Description

Short technical summary and product information.

The Weidmüller WDU 2.5 (part number 1020000000) is a feed through terminal block from the W-series, designed for reliable and compact wiring in industrial control panels. It features a screw termination style, accepting solid and flexible conductors from 0.5 to 4 mm² (26-12 AWG). The terminal block is rated for 25 A (CSA 20 A, ATEX 21 A) and 600 V (CSA 600 V, IECEx/ATEX 550 V), making it suitable for a wide range of power distribution and signal wiring applications.

 

The component is molded from beige Wemid insulation material, offering a flammability rating of V-0 per UL94 and an operating temperature range of -50°C to +120°C. The 2-position, single-level design has a 5.1 mm pitch and side connection direction. Mounting is achieved via a snap-on mechanism onto TS35 DIN rail, simplifying installation and removal. The package quantity is 100 pieces.
