Berker Fuses
Fuses don’t get attention until something goes wrong. And when they do, you want ones that fail safe, replace fast, and don’t cause collateral damage. That’s what Berker fuses are made for — precision, reliability, clarity.
Why a good fuse matters
A fuse is your last line of defense in electric systems. A wild overload or short circuit hits, and only a properly rated fuse keeps that energy from reaching delicate equipment.
Berker fuses are engineered so that the failure mode is predictable: the fuse goes, nothing else burns. That’s real protection.
They meet standard characteristics, thermal behavior, and interruption ratings — no “marketing exaggerations.” And they do it in form factors you actually use.
Berker Cylindrical fuses and glass fuses 5×20
For many installations — lighting circuits, small control lines — Berker cylindrical fuses or glass fuses 5×20 mm are still the workhorses.
They’re easy to inspect (you literally see the link), easy to replace, and compatible with standard fuse clips and holders.
Berker’s versions ensure the glass doesn’t brown out, the filament link doesn’t degrade early, and the contact ends stay tight over years of vibration.
These small fuses serve with minimal fuss, and that’s exactly what you need where reliability is more important than flash.
Berker Micro and fast-acting fuses
Where circuits are sensitive — electronics, control boards, sensor lines — you need Berker micro fuses and fast-acting fuses.
These are built to open quickly when a spike or overload hits, protecting delicate downstream components before they feel damage.
Berker’s fast-acting types (sometimes labelled “F”) offer low I²t and minimal let-through energy. That means your sensitive gear sees less transient stress.
Berker Time-delay and slow-blow types
Not all circuits need an instant cut. Motors, transformers, and inductive loads draw high inrush current at start. That’s where time-delay fuses (often “T” or “gG type” delay) shine.
Berker’s time-lag fuses handle those surges but open under sustained faults. They reduce nuisance blowouts in big systems.
Combining fast-acting and time-delay types in a panel gives you protection tuned to the function of each branch
Berker NH / HRC (high rupture capacity) fuses
For heavier power circuits and mains protection, Berker offers NH fuses and HRC fuses (High Rupture Capacity).
These are built to interrupt very high fault currents safely. The casing, arc-chutes, and contacts are all engineered for energy control — not just “blow and hope.”
Installers appreciate that Berker HRC / NH types don’t flare or vaporize parts. They enclose the arc, extinguish it cleanly, and leave the rest of the system intact.
Automotive and fuse links (GG)
Need protection in distribution panels or special circuits? Berker automotive fuses and fuse links GG (general purpose) cover those niche cases.
They let you apply the same logic and brand reliability across different voltage systems.
These fuses are compact, consistent, and match the same quality standards as their larger partners — so your system doesn’t have a weak link in the chain.
Choosing the right fuse — practical tips
- Match characteristic to load: sensitive electronics = fast-acting; motors/transformers = time-delay.
- Check rated voltage and current — don’t undersize or oversize carelessly.
- Interrupting capacity matters — use NH/HRC in high fault zones.
- Use spare slots — always plan some reserve.
- Mount in proper holders — good contacts make as much difference as the fuse itself.
