LV fuse cutouts provide reliable, standards-compliant overcurrent protection from 32A to 400A for industrial, commercial, and utility networks.
WANGYUAN LV Fuse Cutout with Fuse Link are designed for overcurrent protection in low-voltage distribution networks. Made of durable engineering plastic housing with brass or copper alloy contacts and ceramic/glass fuse elements, the modular plug-in structure ensures reliable circuit interruption and safe field maintenance. Available in multiple current ratings from 32A to 400A, all products comply with relevant international standards, suitable for industrial, commercial and utility low-voltage applications.
Introduction
The cutout bases and fuse carriers shall have the following current ratings at 230/400V: Three phase and neutral for transformers up to 500kVA: 400A; and Three phase and neutral for transformers above 500kVA:630A.
Housing
The outer housing of the units shall be comprised of Grey insulating material of sufficient mechanical strength as to prevent it from becoming damaged. The material shall be resistant fo ultra violet degradation and have flame retardant properties. The Grey colour shall be RAL 7035 code system according to DNA (German Standards Board, Frankfurt, Germany).
Fuse Carrier
The fuse carrier shall be required to take J.? type cartridge fuse links with 82mm centers, conforming to BS 88. Tightening screws shall have insulated tops to enable the fuse carrier to be removed without safety devices (rubber gloves, etc.)

The ceramic/glass fuse link with precision-calibrated fuse element delivers stable overcurrent interruption. Silver-plated copper contacts ensure low contact resistance and consistent tripping performance across the rated range.
The engineering plastic housing offers high impact resistance and dimensional stability under thermal cycling. Robust terminal connections and spring-loaded contacts maintain secure clamping under vibration and load fluctuations.
All metal contacts are silver or nickel plated with anti-oxidation treatment for long-term reliability. The sealed housing and insulated pull-rod sleeve protect internal components from moisture, UV and environmental contaminants.
Modular plug-in design enables quick fuse link replacement without tools. The remote pull-rod mechanism allows safe operation from a distance, compatible with standard LV distribution panels and pole-mounted configurations.
High-grade ceramic stay insulators with brown glazed surface for electrical insulation and mechanical fixation in overhead guy wire systems.
LV fuse cutouts with silicone rubber insulator and drop-out design for overload and short-circuit protection and visible isolation on pole transformer...
57 Series Line Post Insulators use ceramic glaze and galvanized steel fittings for overhead line insulation and support.
