Weidmüller 1004260000 SIHA 3/G20 BL Fuse Holder

The Weidmüller 1004260000 SIHA 3/G20 BL is a fuse holder designed for feed-through modular terminals, giving engineers a compact and structured way to integrate fuse protection into terminal-based wiring systems. In industrial control cabinets and modular terminal assemblies, fuse holders like this are important because they allow circuit protection to be placed exactly where it is needed, without creating unnecessary complexity in the wiring architecture. Instead of treating protection as an afterthought, the use of a dedicated fuse holder helps turn protection into an organized part of the terminal design itself.

What this product is designed for

The Weidmüller 1004260000 SIHA 3/G20 BL is identified as a pluggable fuse holder for feed-through modular terminals. The blue housing makes it easy to distinguish in a terminal strip, which is helpful in maintenance-heavy environments where visual clarity matters. The product is rated at 6.3 A and uses flame-retardant Wemid material with V-0 behavior. This combination makes it suitable for structured low-voltage protection tasks in terminal-based connection systems. {index=12}

Why fuse holders matter in modular terminal systems

A fuse holder is not just an accessory. In many industrial systems, it becomes a central part of circuit organization. It helps isolate faults, supports selective protection, and allows technicians to understand the protective path more easily during service. The Weidmüller 1004260000 SIHA 3/G20 BL fuse holder is especially relevant where compact modular terminal assemblies must include overcurrent protection without sacrificing layout discipline. Search demand around terms like terminal fuse holder, DIN terminal protection, and Weidmüller fuse holder reflects how common this requirement remains in industrial control design.

Dimensional and practical advantages

According to the product data, the SIHA 3/G20 BL has a width of 6 mm, a height of 33.38 mm, and a depth of 45.69 mm. Those compact dimensions matter because terminal assemblies are often constrained by cabinet space. A slim fuse holder helps preserve channel density while still giving the designer a defined protective function. In maintenance terms, a pluggable format also supports easier access and replacement. That can make troubleshooting faster and reduce disruption during service work.

Where this fuse holder is commonly used

This Weidmüller fuse holder is relevant in control cabinets, machine wiring systems, building automation panels, interface strips, industrial power distribution subcircuits, and modular terminal assemblies where circuit protection needs to be integrated cleanly. It works well in designs that value order, readability, and service-friendly protection logic.

FAQ

What is the Weidmüller 1004260000 used for?

It is used as a fuse holder for feed-through modular terminal systems, allowing fuse protection to be integrated directly into terminal-based wiring layouts.

Why is the blue housing useful?

The blue color helps with identification inside terminal strips and can improve maintenance clarity in larger control panel assemblies.

Is this a full terminal block or an accessory?

It is a fuse holder accessory designed to work with feed-through modular terminal concepts rather than acting as a standalone general terminal block.

Why do compact dimensions matter for fuse holders?

Because terminal strips often operate in limited cabinet space. A narrow fuse holder helps preserve density while adding protection where needed.

Where is the SIHA 3/G20 BL most relevant?

It is especially relevant in industrial control panels, automation systems, and modular terminal assemblies that need accessible, organized fuse protection.
