Darbe gerilim koruma cihazı yük ayırıcıyla birlikte bağlandı.

Because Turkish normally puts the verb at the end.

So in:

Darbe gerilim koruma cihazı yük ayırıcıyla birlikte bağlandı.

the final verb is bağlandı = was connected.

A very literal English-style breakdown would be:

• Darbe gerilim koruma cihazı = surge protection device
• yük ayırıcıyla birlikte = together with the load disconnector
• bağlandı = was connected

This verb-final order is one of the most important word-order patterns in Turkish.

The subject is:

Darbe gerilim koruma cihazı

This whole noun phrase is the thing that was connected.

So the structure is essentially:

• Subject: Darbe gerilim koruma cihazı
• Accompanying phrase: yük ayırıcıyla birlikte
• Verb: bağlandı

Even though English often needs the or a, Turkish does not use articles in the same way, so the noun phrase can stand on its own.

This is very common in Turkish, especially in technical language. Turkish often builds long noun phrases by stacking nouns and modifiers.

Here is the phrase piece by piece:

• darbe = impulse / surge / shock
• gerilim = voltage
• koruma = protection
• cihazı = device

Together, they form a technical compound meaning something like:

surge voltage protection device
or more naturally in English, surge protection device

The last word, cihazı, is the head noun, and the earlier words narrow down what kind of device it is.

This kind of compact noun stacking is very normal in Turkish.

Because this is part of a noun compound.

In Turkish, when one noun modifies another noun, the second noun often takes the 3rd person possessive-looking ending -(s)ı / -(s)i / -(s)u / -(s)ü.

For example:

• koruma cihazı = protection device
• su şişesi = water bottle
• araba kapısı = car door

So here:

• koruma cihazı = protection device

Then that whole phrase is further specified by gerilim and darbe.

This ending does not necessarily mean actual possession here. It is just how many Turkish noun compounds are formed.

Yük ayırıcıyla means with the load disconnector.

It is made from:

• yük ayırıcı = load disconnector / load-break switch
• ile = with

In Turkish, ile often attaches to the previous word instead of standing separately.

So:

• yük ayırıcı ile
  becomes
• yük ayırıcıyla

Because the word ends in a vowel, ile changes into -yla / -yle when attached.

So this is a very common pattern:

• araba ile → arabayla = with the car
• öğretmen ile → öğretmenle = with the teacher
• yük ayırıcı ile → yük ayırıcıyla

Good question. İle already means with, so in theory yük ayırıcıyla is enough.

But birlikte adds the sense of:

• together
• together with
• along with

So:

• yük ayırıcıyla = with the load disconnector
• yük ayırıcıyla birlikte = together with the load disconnector / along with the load disconnector

In many sentences, ile and birlikte appear together for emphasis or natural style. This is very common in both spoken and written Turkish.

Bağlandı comes from the verb bağlanmak.

Related forms:

• bağlamak = to connect / attach / tie
• bağlanmak = to be connected / to get connected / to be attached

So bağlandı means:

• was connected
• got connected
• was attached

Grammatically, it contains:

• bağlan- = verbal stem
• -dı = past tense

The full meaning in context is most naturally was connected.

For a learner, the easiest way to understand it is: yes, it works like a passive meaning here.

Compare:

• Cihazı bağladılar. = They connected the device.
• Cihaz bağlandı. = The device was connected.

In this sentence:

Darbe gerilim koruma cihazı ... bağlandı.

the focus is on the device and the result, not on who did the action.

In technical and formal Turkish, this kind of agentless wording is very common, just like English technical writing often says was connected, was installed, was tested, and so on.

Because Turkish does not have definite articles like English the.

So:

• cihaz can mean device, a device, or the device
• the exact English translation depends on context

In technical instructions or reports, Turkish often leaves definiteness unstated unless something else makes it clear.

So Darbe gerilim koruma cihazı can be translated naturally as:

• the surge protection device
• or sometimes a surge protection device

depending on context.

Not very naturally.

A very literal version would be something like:

Surge voltage protection device with the load disconnector together was connected.

That sounds unnatural in English, even though it follows the Turkish structure more closely.

A natural English translation would be:

• The surge protection device was connected together with the load disconnector.
• The surge protection device was connected along with the load disconnector.

So when translating Turkish, it is usually better to keep the meaning rather than the exact word order.

Yes, very typical.

It has several features that are common in technical Turkish:

• long noun compounds
  (darbe gerilim koruma cihazı)
• instrument/accompaniment marking with -yla / -yle
• formal/impersonal verb choice
  (bağlandı = was connected)
• compact wording without articles

Technical Turkish often sounds dense because a lot of information gets packed into noun phrases before the final verb.

Yes. Both are correct.

These mean the same thing:

• yük ayırıcıyla birlikte
• yük ayırıcı ile birlikte

The first is just the attached form, which is very common and natural.

Turkish often allows both:

• arkadaşıyla / arkadaşı ile
• arabayla / araba ile
• yük ayırıcıyla / yük ayırıcı ile

In most contexts, the attached form sounds smoother and more natural.

Yes, Turkish word order is flexible, although the verb usually stays at the end.

For example, the original sentence is neutral:

Darbe gerilim koruma cihazı yük ayırıcıyla birlikte bağlandı.

If you move yük ayırıcıyla birlikte earlier, you can slightly change the emphasis:

Yük ayırıcıyla birlikte darbe gerilim koruma cihazı bağlandı.

Both are grammatical, but the emphasis shifts a little.

Turkish often uses word order to highlight what is more important or what comes first in the speaker’s mind.
