Technical Overview

The Weidmüller WSI 6/LD 10-36V LLC is a specialized fuse terminal block engineered for reliable circuit protection in industrial control systems. It utilizes a screw connection mechanism compatible with wire cross-sections from 0.5 mm² to 10 mm² (AWG 22-8) and houses a standard 5x20mm G-Si fuse cartridge. A distinguishing feature is the integrated LED status indicator, designed to operate within a 10-36V AC/DC range, providing immediate visual feedback on fuse integrity. Constructed from high-quality Wemid material with a UL 94 V-0 flammability rating, this terminal block offers robust performance in temperatures ranging from -60°C to 130°C. It is designed for mounting on TS 35 DIN rails and carries comprehensive approvals including CE, ATEX, and IECEx for global compliance.
