SKU: Weidmuller-1010100000
Price: 3.56 USD
Availability: InStock

Technical Overview

The Weidmüller WPE 4 (Part Number: 1010100000) is a protective earth (PE) terminal block featuring a robust screw connection system. Designed for industrial safety, it establishes a secure electrical and mechanical connection between copper conductors and the mounting support plate (earth). The terminal block is constructed from Wemid, a high-quality thermoplastic with a UL 94 V-0 flammability rating, and comes in the standard green/yellow protective earth color identification. It supports a rated cross-section of 4 mm² and is engineered for mounting on TS 35 DIN rails. With a rated short-time withstand current of 480 A and compliance with IEC 60947-7-2, it ensures reliable grounding in demanding environments. The unit features an M2.5 center screw for the PE connection and accommodates a wide range of wire sizes from 26 AWG to 10 AWG.
