ETI Breakers
There’s no magic in a circuit breaker — it either works when it should or it doesn’t. And when it doesn’t, you find out fast.
ETI breakers have earned their place in panels because they do one thing consistently: protect the system without false trips or slow response. You wire them, close the door, and forget they’re there — until something overloads, and they quietly save the day.
The everyday workhorse ETI miniature breakers (MCB)
Most projects start with the basics. ETI miniature circuit breakers (MCB) are what you’ll see everywhere — offices, shops, homes, light industry. They trip fast on overload, handle short circuits, and reset cleanly.
What’s nice is how stable they feel. The toggle has that firm click — not the soft “maybe” kind.
Inside, the bimetal and magnetic trip units are calibrated precisely, so you don’t get nuisance trips every time voltage spikes or a motor starts.
ETI offers the full range: B, C, D characteristics, 1 to 4 poles, up to 63 A. You can mix them in rows, use common busbars, or pair them with accessories like auxiliaries and shunt trips — everything fits cleanly on the DIN rail.
For the heavy stuff — molded case circuit breakers (MCCB)
When you move beyond small panels, you need muscle. That’s where ETI molded case circuit breakers (MCCB) come in. These are built for industrial loads, main feeders, and large distribution boards.
Solid handles, adjustable trip settings, and the kind of terminals that actually clamp 50 mm² cable without drama.
You can set thermal and magnetic thresholds precisely — no guessing, no field hacks.
And when a fault hits, they open fast and stay safe. The arc chambers are designed to contain and extinguish the arc instantly, not spit metal dust all over your enclosure.
Installers like MCCBs because they’re predictable. You size them once, and they just run — no need for weekly “why did it trip again?” calls.
Low-voltage and power distribution breakers
In the lower tiers of distribution boards, ETI power circuit breakers and low-voltage breakers take over.
They protect feeders, sub-panels, HVAC lines, lighting zones — wherever you need reliable, repeatable disconnection.
You’ll find ETI breakers in a lot of European switchboards because they hit the sweet spot: IEC-certified, affordable, and mechanically robust. The mounting frames are square, the contacts line up tight, and labeling’s clear enough that your techs don’t waste minutes decoding circuit numbers.
Accessories that actually help
Breakers aren’t standalone. ETI makes breaker accessories that make life easier: auxiliary contacts, signal outputs, shunt trips, undervoltage releases, interlocking kits.
Everything mounts without fighting the housing — slide, snap, done.
Need to tie multiple MCBs together or create a shared trip? There’s a kit for that too.
The consistency between series is what saves time — the accessory from one line fits the next, and you don’t need to relearn assembly every project.
Built for real-world reliability
In practice, you notice little things. The screw heads don’t strip. The labels stay readable. The busbar cutouts line up perfectly. That’s why electricians keep using ETI.
Even after years, toggles don’t loosen, contacts stay strong, and the plastic doesn’t yellow from heat.
They’re tested for endurance, short-circuit resistance, and mechanical wear — and it shows.
