|releases when de-energized|
is the best/clearest I can think of.
The door holder doesn't break any current; when the current stops (signal from control system, breaking of fusible link under heat, etc.), the electromagnet is de-energized and a spring closes the door, which therefore breaks wind.

I think if the fusible link were to be part of the door holder they could dispense with electrical control and simply have a catch held in place by a spring-loaded line with a fusible link: when the link goes, the spring releases the catch and the door closes under another spring.
PS I make man-traps in my spare time.

It refers to fail-safe (i.e. fail-close) electromagnetic door-stops, which can be used to hold a door in the open position when energised, but when the current is broken (power failure or fire-alarm command) the door is released and closes automatically (powered by a spring device, or whatever).

Re Asker's note below: Errr.... actually, that webref you 'found to back it up' was the very first one listed in my original answer :) Hey - but who am I to quibble???
That said, the webref "Automatically closes fire doors by current breaking..." is factually incorrect: The mere breaking of the current doesn't close the door - it just releases it, rendering it closeable by some other means.

|Notes to answerer|
|Asker: Thanks, that is brilliant. I have now found the following to back it up:
"Electromagnetic door holder. Automatically closes fire doors by current breaking ..."
| |2 days 22 hrs confidence:
From the reference below: "The only accepatable method of holding open fire doors is by using a device that meets the requirements of BS 7273: Part 4 and BS 5839: Part 3 in its operation. These a generally Electro-magnetic door hold opening (referred to as Automatic Door Release Mechanism (ADRM)) devices that are connected to the buildings alarm system.
A translation in the same format as "une ventouse electromagnétique (à rupture)", just doesn't work in English.
"Electro-magnetic door hold opening device" or "Automatic Door Release Mechanism" are probably the best options. I would choose the latter as being closest to the French.
