Weidmüller 1005250000 SIHA 3/G20/LD 10-36V BL Fuse Holder for Modular Terminal Protection
The Weidmüller 1005250000 SIHA 3/G20/LD 10-36V BL fuse holder belongs to a product category that plays a quiet but highly practical role in industrial terminal assemblies. In control panels and distribution systems, protection is not only about the fuse itself; it is also about how the fuse is integrated into a terminal architecture that remains organized, serviceable, and easy to identify. That is where a fuse holder designed for feed-through modular terminals becomes valuable.
The Weidmüller SIHA 3/G20/LD 10-36V BL fuse holder is described as a pluggable fuse holder for feed-through modular terminals. It is supplied in blue, built from Wemid, and specified at 2.31 A with a V-0 flammability class. These details are not cosmetic. Together, they show that the part is intended for structured terminal-level protection where material behavior, current handling, and maintenance convenience all matter.
Understanding the Product Type
When engineers specify a Weidmüller 1005250000 SIHA 3/G20/LD 10-36V BL fuse holder, they are typically addressing a panel-level need for compact overcurrent protection integrated into a terminal arrangement. Instead of using a separate inline holder elsewhere in the cabinet, a terminal-compatible fuse holder keeps the protective element close to the circuit path and easier to trace during maintenance.
The fact that this version is pluggable adds operational value. In service environments, quick replacement and simplified inspection are important. A pluggable component format can help reduce downtime and make circuit troubleshooting more straightforward, especially in installations where multiple protected channels are grouped in a dense terminal rail layout.
Technical Details That Matter
The official product information identifies the Weidmüller SIHA 3/G20/LD 10-36V BL fuse holder as a fuse holder for a feed-through modular terminal, with a nominal current figure of 2.31 A. The housing material is Wemid, and the flammability classification is V-0, which is highly relevant in industrial control cabinet design because it supports material performance expectations in safety-conscious installations.
Dimensional data also gives useful planning context. This model is listed at approximately 63.1 mm depth, 39.38 mm height, and 6 mm width. That slim width is especially important in modern panel engineering, where channel density is often high and every millimeter on the DIN rail counts. The blue color can also support visual differentiation in terminal layouts where installers rely on color coding for quick circuit recognition.
Why Material Class and Form Factor Are Important
In industrial environments, the physical qualities of a terminal accessory matter almost as much as the electrical ratings. A Weidmüller 1005250000 SIHA 3/G20/LD 10-36V BL fuse holder made from Wemid with V-0 performance is well aligned with cabinet applications that prioritize structured design, robust insulation properties, and predictable behavior under standard industrial conditions.
The compact, pluggable format makes the product relevant not only for new panel builds but also for retrofit projects where engineers need to add fused protection without redesigning an entire terminal section. This is particularly useful in automation panels, signal distribution assemblies, and power segmentation layouts where individual channels must remain easy to isolate and service.
Use Cases in Real Panel Design
The Weidmüller SIHA 3/G20/LD 10-36V BL pluggable fuse holder fits well in machine control cabinets, building automation panels, process instrumentation interfaces, and other terminal-heavy assemblies. In these contexts, designers want a protective component that integrates neatly with terminal block architecture rather than creating extra wiring complexity.
Another reason this product type is relevant is maintainability. When protection is integrated directly at the terminal level, technicians can inspect the layout more intuitively. That makes documentation, troubleshooting, and replacement workflows more consistent over the life of the system.
Why This Product Is More Than a Small Accessory
Accessories like this are easy to overlook, but they have a direct effect on operational clarity. The Weidmüller 1005250000 SIHA 3/G20/LD 10-36V BL fuse holder contributes to protection, panel order, and service efficiency in a single compact element. In high-density panels, that kind of component-level discipline supports better engineering outcomes across the entire assembly.

Weidmüller 1005250000 FAQ
What is the Weidmüller 1005250000 SIHA 3/G20/LD 10-36V BL used for?
It is used as a fuse holder for feed-through modular terminals. Its role is to integrate fuse-based circuit protection into terminal layouts in a compact, organized, and service-friendly way.
Why is the pluggable design important?
A pluggable design simplifies installation, replacement, and maintenance. In practical panel work, that means faster access during service and easier handling when a protective element needs to be checked or changed.
What does the 2.31 A specification indicate?
It identifies the rated current associated with the product’s intended use. This value is important during design review because engineers need to align terminal accessories with the electrical characteristics of the protected circuit.
Why is the V-0 Wemid housing relevant?
V-0 is a flammability classification that supports industrial safety expectations for insulating materials. Wemid is a thermoplastic material used in terminal technology and is valued for suitability in electrical applications.
Does the blue color have a technical purpose?
In many professional panel layouts, color helps identify function, potential grouping, or circuit logic. While color alone does not change electrical performance, it improves readability and maintenance efficiency in structured assemblies.
