Standards

Standards IEC 62208 and EN 50298 lay down definitions,
classifications, characteristics and test requirements for enclosures used for switchgear a n d control gear assemblies.
They apply to empty enclosures before installation of the devices
by the panel builder, as supplied by the manufacturer.
They apply to one – piece enclosures and to enclosures supplied in
kit form.

Type tests of standard EN 50298

1. Static load
2. Hoisting
3. Axial loads of metal insters
4. IK code
5. IP code
6. Thermal stability
7. Resistance to heat
8. Resistance to abnormal heat and to fire
9. Dielectric strength

Electrical Switchboards up to 4000 A

The PrismaSeT P functional system can be used for all types of low-voltage distribution switchboards (main, subdistribution and final) up to 4000 A, in commercial and industrial environments

Switchboard design is very simple

1. A metal structure

The switchboard is made up of one or more frameworks combined side-by-side or back-to-back, on which a complete selection of cover panels and doors can be mounted.

2. A distribution system

Horizontal busbars or vertical busbars positioned in a lateral compartment or at the rear of the cubicle are used to distribute electricity throughout the switchboard.

3. Complete functional units

• a dedicated mounting plate for device installation
• a front plate to block direct access to live parts
• prefabricated busbar connections
• devices for on-site connections.

Each functional unit contributes to a function in the switchboard. The functional units are modular and are arranged rationally. The system includes everything required for functional unit mounting, supply and onsite connection.

The components of the PrismaSeT P and those of the functional units in particular have been designed and tested taking into account device characteristics. This design approach ensures a high degree of reliability in system operation and optimum safety for personnel.

Assets of PrismaSeT P Switchboards

1. A dependable electrical installation

The total compatibility of Schneider Electric devices with the PrismaSeT P is a key advantage in ensuring a high level of installation dependability.

2. An upgradeable electrical installation

Thanks to modular design, PrismaSeT P switchboards can be
modified easily to integrate new functional units as needed.
Maintenance operations, carried out with the switchboard deenergised, are fast and straight-forward due to easy access to
devices

3. Total safety for personnel

Work in a switchboard must be carried out by authorised
persons in compliance with all applicable safety regulations.
To increase the safety of personnel, devices are installed behind
protective front plates; only the operating handles are accessible.

Additional internal protection (partitions, barriers) is available to
create form 2, 3 or 4 separation to protect against direct contacts
with live parts.
Terminal shields are mandatory for installation of Compact NSX
and INS/INV devices in PrismaSeT P enclosures

4. Connected Solution

• Fire prevention
• Power availability
• Energy management

Electrical switchboards up to 4000 A

System design has been validated by type tests as per standards
IEC 61439-1 and 2 and benefits from the combined experience of Schneider Electric
customers over many years.

See “How to assemble an electrical switchboard” Guide DESW043EN Electrical switchboards built using the PrismaSeT P functional system and Schneider Electric recommendations fully comply with international standards IEC 61439-1 and 2.
