Overview

The Mersen SI 6x32 Fuse Holders (SKU: E091728) are precision-engineered for industrial-grade protection of ferrule-type fuses (6.3x32 mm) in high-voltage applications. Compliance with IEC 60647-3 ensures adherence to global safety standards for fuse holders, making these units suitable for demanding electrical installations. Designed for mounting on 35mm DIN-rails—both symmetric and asymmetric configurations—the SI 6x32 fuse holders provide a secure and space-efficient solution for panel mounting. The IP2x protection rating safeguards against accidental contact with live parts, reducing the risk of electrical hazards during maintenance or operation. Constructed from self-extinguishing V0-class material (UL94), these fuse holders enhance fire safety by resisting ignition and flame propagation. Silver-plated copper clips with elastic clamping ensure low-resistance electrical connections, minimizing heat buildup and ensuring reliable performance over time. The 6.3mm clip clamp with a locking cover prevents accidental disconnection, while an optional padlocking device and LED blown-fuse indicator (available upon request) add operational flexibility and quick fault detection. For environments exposed to corrosive elements, a salt spray-proof version is available, extending the product’s lifespan in harsh conditions. Ideal for industrial applications such as motor drives, UPS systems, and small inverters, the SI 6x32 fuse holders deliver robust protection up to 750 volts. Their modular design and compatibility with standard ferrule-type fuses make them a versatile choice for panel builders and system integrators. With verified dielectric strengths exceeding 2500V and a maximum fuse current rating of 30A, these fuse holders are engineered for reliability in critical power distribution systems.
