Fuseholder · 30A 3-pole 100-750V AC midget fuse without indicator · ITC Electrical 401.203

SKU: ITC-401.203

3-pole modular fuseholder for midget fuses rated up to 30A with a 100-750V AC rating. Commonly used in industrial control panels and machinery where a dead-front fuseholder is needed for branch or control circuit protection.

What this product is for

This fuseholder is for mounting and isolating midget fuses in industrial control panels, machinery, and OEM assemblies. It is a 3-pole modular dead-front fuseholder intended for applications requiring up to 30A fuse protection.

Use for

Use for industrial panels, machine control circuits, and equipment builds that require a 3-pole midget fuseholder with CSA and cURus certification. It accepts copper conductors from 18-8 AWG (0.75-16 sq mm) and is suited to DIN-style modular panel layouts.

Avoid for

Avoid using this fuseholder where a blown-fuse indicator is required, where photovoltaic DC ratings are needed, or where fuse type and voltage class do not match the holder. Do not use it as a substitute for a complete fused disconnect unless the assembly is designed and approved for that purpose.

Best for

Best for electricians, panel builders, and maintenance teams needing a compact 3-pole fuseholder for midget fuse applications in industrial environments. It is a practical choice when you need modular assembly and front-access fuse replacement.

Installed in

Typically installed in electrical enclosures, industrial control panels, OEM machinery, and automation cabinets. The body width is 52.5 mm (about 2.1 in), closed height is 58 mm (about 2.3 in), and open height is 74.8 mm (about 2.9 in).

Why this product exists

This product provides a safe, modular way to mount and replace midget fuses in multi-pole circuits. The dead-front design helps reduce accidental contact during normal service access, and the modular format supports organized panel layouts.

Compared with similar products

Compared with indicator versions, this model does not include neon or LED blown-fuse indication. Compared with 1-pole or 2-pole versions, this 3-pole model is better suited to three-phase control or protection arrangements using midget fuses.
