Weidmüller Fuses

weidmuller fuses range and buyer’s map

Compact protection for control circuits, field loads, and instrumentation. Weidmüller structures the category by format (5×20 mm, 6.3×32 mm glass/ceramic, NH mini, CF8 blade, and electronic micro-fuse), mounting (DIN-rail carriers, panel clips, in-line), and indication (pop-up flag or LED). Typical buyers are OEM panel shops, machine builders, and MRO teams who need fast, standardized protection that matches TS35 rails and common terminal pitches.

Product range and series overview

Families split into DIN-rail fuse carriers with screw or push-in terminals, compact in-line bodies for field harnesses, and high-rupture links for DC drives and servo auxiliaries. Popular movers: 5×20 mm carriers with LED blow indicators, 6.3×32 mm versions for higher currents, and slim single-pole holders that line up like terminals to save rail space. Most distributors stock P-series push-in carriers first; screw-clamp mirrors are available for legacy plants. Kits come with clips, spare tubes, and labeling strips for quick identification.

weidmuller fuse holders sizes and mounting

Choose 5×20 mm for PLC I/O and sensor loops, 6.3×32 mm for valve banks and relays up to ~10–12 A per branch, and compact NH mini for beefier auxiliaries. Bodies are finger-safe, IP20 front, with captive covers and clear windows. Mounting is TS35; end-stops and partition plates keep heat spacing correct. Terminations: push-in for rapid build, screw for mixed copper sizes, spring for vibration zones. Options include LED status and touch-safe pullers for tool-less swap.

Key features and options

• Voltage bands that actually matter: 250 VAC and 24/48 VDC auxiliaries, with selected DC-rated carriers for battery and drive cabinets.
• Current range: typical 0.5–20 A per pole (glass/ceramic), higher in NH mini formats.
• Indication: mechanical flag or LED to cut fault-finding time.
• Connections: 2-pole jumpers for common feeds; test ports for live checks without removal.
• Accessories: rail end-stops, markers, pre-terminated pigtails, and spare-fuse parking.

weidmuller modular fuse systems panel and field builds

For multi-circuit distribution, modular carriers gang side-by-side with plug-in jumpers to create tidy feeders for sensors, valves, and small motors. You can pre-build assemblies by function (I/O, pneumatics, safety relays) and label per circuit. Installers prefer mixed decks: top row fused positives, bottom row common returns using matching terminals for clean routing. For field wiring, compact in-line bodies with screw caps ride inside IP-rated junction boxes.

Applications and compatibility

Used in packaging machines, conveyors, process skids, HVAC AHUs, bottling lines, and warehouse systems. Pair holders with Weidmüller A-/W-series terminals on the same rail, RockStar connectors for quick machine splits, u-remote slices for I/O islands, and PRO power supplies. For clean builds, add cable glands sized to M16/M20 and pre-cut markers to match your schematic tags.

Integration with other brand products

Carriers align with TS35 rails used by Weidmüller terminal blocks; jumpers match common 2-pole bus spacing. LED-indicated versions share 24 V rails with PLCs without nuisance glow. Use the same ferrule sizes and screwdriver families as your terminals, simplifying toolkits and training.

weidmuller safety fuses selection in real projects

Where safety relays and e-stops require selective coordination, fit fast-acting glass/ceramic tubes on the logic side and time-delay types for inductive valve banks. For DC motion auxiliaries, choose high-DC-rated tubes or NH minis to handle fault energy without welding. In retrofit jobs we see teams standardize on two tube sizes and three ratings to keep spares lean.

Selection criteria for B2B clients

• Circuit type: electronics need fast-acting; coils and small motors prefer time-delay to ride inrush.
• Voltage and DC rating: verify the DC interrupt spec when protecting drives or batteries.
• Current and discrimination: size 125–150% of steady load so upstream mains breakers remain selective.
• Holder format: choose DIN-rail carriers for panels; in-line bodies for field boxes and harness repairs.
• Indication need: LED flags pay off on large cabinets and night shifts—faster fault location.
• Service model: push-in holders speed swap during TPM windows; screw types tolerate mixed conductor sizes.

Advantages of working with Bankoflamps

Expect individual B2B pricing, a personal account manager, and real-time EU stock visibility. Quotes turn fast (around an hour), orders drop by EAN/MPN, and price lists are downloadable with validity dates. Track lead times and shipment consolidation, get order status and analytics, and use post-payment up to 30 days for trusted clients. We serve France, the Baltics, Germany, Spain, Italy, Belgium, and the Netherlands.

Reliability, operation, and field data

Common returns stem from under-rating coils or missing DC interrupt specs, not from the holders themselves. Keep spare tubes clipped inside the panel door; many carriers include parking slots. Torque terminals correctly and use ferrules—loose strands create heat. For warm cabinets, leave one pitch of space every 8–10 poles or add a partition plate to improve thermal performance.
