Do you offer customized configurations or branding?

Yes. We support OEM/ODM on pole count, current rating, indicator type, housing color, and printed branding, and we can pre-assemble holders with matched fuse links. Provide your specification and artwork for a sample and lead-time confirmation.

Which standards do your fuse holders and links meet?

Holders and links are built to the IEC 60269 series — including IEC 60269-6 for gPV solar links — with CE and RoHS conformity and test reports per model. Confirm your destination market so we can advise on any additional national requirements.

What is your sample and MOQ policy?

Paid samples are available for qualification, typically credited against the first order. Standard holders carry a low MOQ, while custom configurations and OEM branding require a higher minimum. Request a model-specific quotation to proceed.

DC Fuse Holder & Fuse Link Buying Guide for Global Procurement

The single most common — and most dangerous — procurement error in this category is applying an AC-rated fuse holder to a DC circuit. DC current has no natural zero crossing, so the holder and fuse link must be explicitly rated for the DC voltage and breaking duty of the application. Confirm the rated voltage (typically AC 690 V or DC 500–1000 V), the rated current (32 A, 63 A, or 125 A), and the fuse-link footprint: 10×38 mm, 14×51 mm, or 22×58 mm. The holder must accept the correct link size and provide touch-safe IP20 finger protection per IEC 60529.

Match the fuse-link class to the load. gG links provide general-purpose line protection per IEC 60269-1/2, aM links are tuned for motor circuits, and gPV links to IEC 60269-6 are mandatory for photovoltaic strings — they provide full-range DC breaking and reverse-current behavior that AC links cannot. For diagnostics, LED blown-fuse indication per pole shortens fault-finding in dense panels. Verify the housing is flame-retardant (UL94 V-0) for installations near energized busbars.

Industry Application Scenarios

Solar PV String Protection

With gPV links rated to 1000 V DC, our holders provide per-string overcurrent and reverse-current protection in combiner boxes and array junctions, with LED indication for rapid identification of a blown string.

Industrial Control & Motor Branches

10×38 mm and 14×51 mm holders with gG or aM links protect control transformers, contactor coils, and motor feeders on the DIN rail, isolating a fault without dropping the whole panel.

Battery Storage & DC Distribution

DC-rated holders safeguard battery banks and DC bus connections, where high prospective fault currents demand a verified DC breaking capacity rather than a re-purposed AC device.

Commercial Distribution Boards

High-current 22×58 mm holders up to 125 A protect sub-mains and large equipment feeds, with per-pole status indicators for fast visual inspection.
