Electrical circuit
Hi - I'm trying to find the best English translation for this. "direct (or immediate) connection, "engagement" etc. This has to do with an investigation of an electrical fire to find the underlying cause. It appears in the following examples:
Kortslutningsvernene har gitt direkte innkobling, forsinket utkobling og gjentatte innkoblinger som kan ha ført til økt kortslutningsbelastning, spesielt for negativfasen.
Linjetest før spenningssetting har flere ganger gitt negativt resultat (indikert feilfri linje) og dermed tillatt direkte innkobling mot en feil.
Ved direkte innkobling mot feil på grunn av negativ linjetest, har vernet detektert kortslutning og startet ny gjeninnkoblingssekvens med automatisk gjeninnkobling etter fem sekunder.
Thanks for your help!

10.7.1 Overcurrent protection
Overcurrent protection devices such as fuses, breakers, and others limit the current to the proper rate and disconnect short circuits. The type of overcurrent protection system used and the maximum current passing through the circuit components determine the size of the overcurrent protection system. The design and size of the overcurrent protection system are outlined by national codes. In many countries, the short-circuit current of the array determines the size of the overcurrent protection devices. The main reason for selecting the short-circuit current of the array is that the PV is a limited current source, that is, the short-circuit current is the highest current produced by this source.
Overcurrent protection devices
Overcurrent protection is critical to personal safety and protection from a number of hazardous conditions that can result from materials igniting due to improper overload protection or short-circuit protection. Additionally, the OCPD guards against explosive ignition and flash hazards from inadequate voltage-rated or improper interrupting-rated overcurrent protective devices. Overcurrent protective devices, or OCPDs, are typically used in main service disconnects, and in the feeders and branch circuits of electrical systems for residential, commercial, institutional, and industrial premises (Figure 5.3).

Dimensioning principles
For each circuit, the dimensioning process comprises the selection of one, or more than one switching/protection device(s) to be used at the beginning or end of a connecting line, as well as the selection of the connecting line itself (cable/line or busbar connection) under consideration of the technical features of the corresponding switching/protection devices. For supply circuits in particular, dimensioning also includes rating the power sources.

Reference:
A short circuit should always cause a breaker to *trip* or a fuse to blow
Short circuit protection is provided by the electromagnet. The electromagnet produces a magnetic field sufficient to pull the armature only when overload amperages are reached. Tripping occurs when the armature strikes the trip bar. This cuts current flow and releases the armature.
A short circuit occurs when current travels along an unintended path, often where essentially no (or a very low) electrical impedance is encountered. Short circuit protection is protection against excessive currents or current beyond the acceptable current rating of equipment and it operates instantly. As soon as an overcurrent is detected, the device trips and breaks the circuit.

Circuit breakers are used in a variety of ways. They are mounted in panelboards to protect branch circuit wiring and they are built into equipment to protect it. With this range of applications, it's not surprising that a circuit breaker must provide both short circuit and overload protection.
Interrupting a short circuit that is limited by the resistance of the wiring is a very severe test of a circuit breaker, and if the interrupting capacity of the breaker is not adequate, the device can literally explode. Overload currents that reach 2 to 5 times the normal rating of the breaker are handled differently, and very often the circuit breaker must carry the current for an appreciable time without tripping.
PROTECTION AGAINST OVERLOADS
Overloads can be short-term or long-term. The protective device chosen must not trip on momentary or short-term overcurrent events that are normal for the piece of equipment it is protecting. Electronic devices, for example, may create inrush currents as their internal power supply and filter circuits start. These inrush currents typically last only a fraction of a second, and seldom cause a problem. https://www.e-t-a.co.uk/resources/white_papers/overload_or_s...

Discussion
The suggestion is to use the word 'direct' connection. (he is asking it is related to a transformer, right? Anyway he told me that the word immediate shall be not used. He speaks English and he is an expert in his field. At least I shall thank you - we had a nice chat :)
