Summary
The object is a vintage electrical switchboard with a backplate of unknown composition. The backplate is moderately likely to contain asbestos, as such materials were common for fireproofing and insulation in older electrical applications. It is recommended to presume the material contains asbestos and have it tested by a professional before any disturbance.
Object description
The image displays a vintage electrical switchboard mounted on a concrete or plaster wall. The assembly includes a main backplate with a marbled pattern, three knife switches with a wooden handle, three white ceramic fuse holders, and visible electrical wiring.

Asbestos Assessment
The primary material of concern is the backplate, which appears to be made of a solid, dense material with a marbled finish. While this could be genuine marble, which does not contain asbestos, electrical panels from this era frequently used asbestos-containing materials for their fire resistance and electrical insulation properties. Suspect materials include asbestos-cement board or asbestos-reinforced plastics or resins. These materials were often manufactured to mimic stone finishes, and without a view of a broken edge or material data, a definitive visual identification is impossible. A secondary potential concern is the insulation of the older electrical wiring connected to the unit. Some vintage wiring systems incorporated asbestos as an insulating wrap or filler, although this cannot be determined from the external appearance shown in the photograph. The ceramic components of the fuses and the wooden handle are not considered likely to contain asbestos.
Recommended action
Given the significant possibility that the backplate contains asbestos, it should be treated as an asbestos-containing material (ACM) until proven otherwise through laboratory analysis. Do not drill, cut, sand, or disturb the panel. If renovation, removal, or repair is necessary, it is strongly recommended that a qualified asbestos professional be consulted to take a sample for testing and to perform any required work under controlled conditions to prevent fiber release.
