General technical information:

With the Prisma P & G, Schneider Electric proposes

high-performance technical solutions, with enhanced robusteness,

looks and aesthetics to produce low voltage electrical

switchboards up to 3200 A, in commercial and industrial buildings.

Prisma P & G switchboards capitalize on the experience gained

over 30 years, during which thousands of switchboards have been

built and operated.

For a dependable electrical installation

Total compatibility between Schneider Electric switchgear devices and the Prisma system helps build dependability into every electrical installation, that has been validated by type tests in compliance with standard IEC 60439-1.

An electrical installation capable of evolving

Modular in structure, Prisma can keep pace with evolving switchboard needs and integrate new functional units as required. Maintenance operations are fast and easy with total access to all switchgear devices.

Total safety for users

Switchgear devices are installed behind a protective front plate that leaves only the operating handle visible.

General technical information

Standard IEC 60364-3 lists and codes a large number of external influences to which an elec-trical installation may be subjected: presence of water, presence of solid bodies, risk of impacts, vibrations, presence of corrosive substances. These influences are exerted with an intensity varying according to installation conditions: the presence of water may be simply a few drops fal-ling…or complete immersion.

Standard IEC 60529 indicates the degrees of protection provided by an enclosure for electrical devices against access to hazardous parts, against penetration of solid foreign objects and against penetration of water.

Degree of protection IP code

These standards do not apply for the protection against the risks of explosion or conditions such a humidity, corrosive vapour, fungus or vermin.

The IP code is made up of two digits and can include an additional letter when the actual protection against access to the hazardous parts is better than that indicated by the first digit.

The first digit characterises the protection provided by the enclosure against the ingress of solid foreign objects.

The second digit characterises the protection provided against the ingress of water with harmful effects.

2nd digit

Protection against ingress of water

1 Protected against vertically falling water drops (condensation)

2 Protected against vertically falling water drops when enclosure tilted up to 15°

3 Protected against spraying water up to 60° from vertical

4 Protected against splashing water from all directions

5 Protected against water jets from all directions

6 Protected against powerful water jets from all directions

7 Protected against the effects of temporary immersion in water

8 Protected against the effects of continuous immersion in water

1st digit

Protection against ingress of solid objects

1 Protected against solid foreign objects larger than 50 mm

2 Protected against solid foreign objects larger than 12.5 mm

3 Protected against solid foreign objects larger than 2.5 mm

4 Protected against solid foreign objects larger than 1 mm

5 Protected against dust (dust protected) 6 Dust tight Ø 50 mm Ø 12,5 mm Ø 2,5 mm Ø 1 mm 15 60
