Classificazione IP
Le classificazioni IP ("Ingress Protection") sono definite nello standard internazionale EN 60529 e valutano il grado di protezione fornito dagli armadi elettrici contro l'ingresso di solidi e liquidi (oggetti, particelle, polvere, acqua, ecc.).
Maggiore il valore di ciascuna cifra, maggiore la protezione.
