BTicino Fuses

You rarely praise a fuse—until it prevents catastrophe. BTicino fuses are the bits you drop in and then forget about, but when something goes wrong, you’re glad they’re engineered right. These aren’t generic components — these are parts designed to keep your panels safe, predictable, and serviceable.

Why pick a good fuse

A bad fuse either won’t blow when it should or blows when it shouldn’t. Either way, trouble. BTicino fuses are designed to fail cleanly — open the circuit, not destroy the board. Their ratings, thermal behavior, and interruption capacity are real, not marketing promises.

Also, the right fuse is a design tool: choose characteristic, speed, and size right, and you protect downstream gear reliably. That’s exactly what BTicino lets you do with confidence.

BTicino Cylindrical & glass fuses 5×20

The workhorse of control circuits: BTicino cylindrical fuses or glass fuses 5×20 mm. These are common in lighting, small relays, signal lines. You see the wire inside (if it’s blown), replace fast, no surprises.

BTicino’s versions make sure the glass is clear, the ends don’t oxidize, and the link doesn’t deform under thermal stress. That means many fault cycles without damage to holders or contacts.

BTicino Micro and miniature fuses

For sensitive electronics and tight spaces, BTicino micro fuses or miniature fuses give you high protection in small form. They react quickly to spikes, but in a controlled way so downstream circuitry is spared.

These are perfect for control cards, instrument modules, monitoring systems — places where space is tight but protection still matters.

BTicino Fast-acting & time-delay types

Not every circuit responds to sudden load the same. BTicino fast-acting fuses (F or “gG” types in some lines) blow immediately on a fault — ideal for sensitive electronics.
Time-delay fuses (slow-blow types) handle surges like startup currents of motors or transformers — they wait a moment before opening under sustained fault.

Choosing the right one (fast vs slow) prevents nuisance trips while still giving safety.

BTicino NH / HRC fuses & high-capacity protection

For heavy-duty circuits you can't babysit, BTicino NH fuses and HRC fuses (High Rupture Capacity) are the armor. They interrupt very large fault currents safely, without scattering molten metal or damaging surroundings.
These are used in mains feeders, distribution panels, primary circuits where safe interruption is non-negotiable.

Fuse links GG, replacement fuses, specialty types

BTicino fuse links GG (general purpose) give broad coverage. You can use them in many branch circuits with predictable behavior.
BTicino replacement fuses are the ones you keep in your kit. Matching them exactly (same characteristic, size, rating) ensures service is smooth. No mismatches, no forced fits.

BTicino also supports specialty fuse types (depending on line) to cover whatever weird circuit your project has.

Practical advice for installs

• Always check both current and characteristic rating (fast, time-delay)
• Use fuses rated for the fault current expected in the panel
• Keep spares (especially common ones) on hand — replacement is often the cheapest downtime
• Use proper holders — good contact matters as much as the fuse itself
• Label everything — by rating and function, so next tech knows what you intended

Supply via Bank of Lamps

At Bank of Lamps, we stock the full BTicino fuse range: cylindrical fuses, NH / HRC fuses, glass fuses 5×20, micro / miniature fuses, fast-acting, time-delay, GG fuse links, and replacement fuses — all available for B2B and wholesale across Europe.

We ship from central warehouses (Germany, Netherlands, Baltics, etc.) with datasheets, spec sheets, and real stock transparency.

Because when a fuse survives fault conditions and protects everything else — that’s not luck. That’s engineering. And BTicino fuses do exactly that.
