Compartmentalised enclosures are used in electrical systems where multiple sections need to be separated within a single structure. When a single enclosure must house equipment operating at different voltage levels  or when safety standards require physical separation between functional sections compartmentalised enclosures are the engineered answer. By dividing the internal space into discrete, sealed sections, these enclosures prevent cross-contamination of electrical faults, simplify maintenance, and help meet IEC Form factors required by many project specifications.
