“In the first book of the Abhidhamma, the Dhammasangani (Buddhist Psychological Ethics), Nibbana is referred to as the unconditioned element, asankhata dhatu (See Appendix II), and it is nama or arupa (non rupa), but it is different from conditioned nama because it does not experience an object. Realities are either nama or rupa, and since nibbana is not rupa it is classified as nama. Kom has explained very clearly about the classification of the four paramattha dhammas. We read in the Atthasalini, Expositor (II, Book II, Part II, Suttanta Couplets, 392) an explanation of nama. Nama is derived from namati, bending towards an object, and it can also be a name. Citta and cetasika bend towards an object and experience an object, and also they cause one another to bend on to the object: “The four khandhas are name (nama) in the sense of bending, for they bend towards the object. In the sense of causing to bend all (of the foregoing, namely nibbana and the four nama khandhas) are ‘name’ (nama). For the four khandhas cause one another to bend on to the object; and nibbana bends faultless dhammas on to itself by means of the causal relation of the dominant influence of the object.” Thus, nibbana does not bend towards an object and does not experience an object, but it is the predominant object condition for the lokuttara cittas that experience it, bending them towards itself in that way.”

“There are citta, cetasika, rupa, and nibbana as ultimate realities. No other things are realities. Only these four are real in their ultimate sense and they are always true at any given time and at anywhere. In the previous pages, citta, cetasika, and rupa have been discussed in some detail. There is a fourth ultimate realities. It is nibbana.”

From the Abhidhammattha-saṅgaha:
"Nibbāna however is termed supramundane, and is to be realized by the wisdom of the Four Paths. It becomes an object to the Paths and Fruits, and is called Nibbāna because it is a departure (ni) from cord-like, (vāna) craving.
Nibbāna is onefold according to its intrinsic nature.
According to the way (it is experienced) it is twofold - namely, the element of Nibbāna with the substrata remaining, and the element of Nibbāna without the substrata remaining.
It is threefold according to its different aspects, namely, Void (60), Signless (61), and Longing-free (62).
Great seers who are free from craving declare that Nibbāna is an objective state (63) which is deathless, absolutely endless, non-conditioned (64), and incomparable.
Thus, as fourfold the Tathāgatas reveal the Ultimate Entities-consciousness mental states, matter, and Nibbāna."
And from ‘the notes’:
Nibbāna is an ultimate reality (vatthu-dhamma) which is supramundane (lokuttara), that is, beyond the world of mind and body or the five ‘aggregates’.

I hope this will suffice.
