1250 A vertical profile for Linergy busbars

The LVS04505 is intended to be part of the Linergy electrical distribution system inside PrismaSeT P switchboards. Its function is to carry and distribute high currents through the main busbar of the switchboard, allowing the necessary connections to be made to the different devices and circuits.

Its 1250 A rated current places it among the Linergy solutions designed for high-power distribution boards, where a busbar system capable of carrying significant currents in an orderly manner and in accordance with Schneider Electric tested configurations is required.

Length of 1,670 mm

The profile has a nominal length of 1,670 mm, equivalent to 1.67 meters. This measurement is specifically designed for compatible vertical configurations in PrismaSeT P switchboards.

The profile length provides a wide vertical distribution area inside the enclosure, making it easier to connect different elements along the busbar according to the electrical design of the switchboard.

Compatible with Schneider Electric PrismaSeT P switchboards

Schneider Electric specifies the LVS04505 for use with PrismaSeT P enclosures. It can be installed in cell configurations of:

• 650 mm width.
• 650 + 150 mm width.

Integration within the PrismaSeT system allows the profile to be combined with supports, connections, and other Linergy components intended to build a complete busbar assembly.

Vertical rear or side installation

The profile is designed for vertical installation, and Schneider Electric provides two operating positions:

• Rear mounting: with the busbar arranged in the rear area of the cell.
• Side mounting: with the profile positioned in the side area of the enclosure.

The selected position and the number of supports used directly affect the permissible short-time current rating of the assembly, so the tested and specified configurations by Schneider Electric must be respected.

Short-time current withstand

The ability to withstand short-circuit currents for one second depends on the profile position and the number of supports used. Schneider Electric specifies the following Icw values for the LVS04505:

Rear mounting

• 3 supports: 25 kA for 1 second.
• 4 supports: 30 kA for 1 second.
• 5 supports: 40 kA for 1 second.
• 7 supports: 50 kA for 1 second.

Side mounting

• 3 supports: 40 kA for 1 second.
• 4 supports: 50 kA for 1 second.
• 5 supports: 60 kA for 1 second.

These values show the importance of using the correct number of supports and respecting the mounting arrangement established by the manufacturer. The final busbar configuration must be selected according to the short-circuit current expected in the installation.

Permissible current according to the switchboard protection rating

In addition to its 1250 A rated operational current, Schneider Electric provides permissible current values at an ambient temperature of 35 °C depending on the enclosure protection rating:

• Up to IP31: 1290 A at 35 °C.
• Above IP31: 1170 A at 35 °C.

These values reflect the influence of ventilation and enclosure sealing on busbar thermal dissipation. Final sizing must be carried out considering the actual switchboard conditions and Schneider Electric tables.

1000 V rated insulation voltage

The profile has a rated insulation voltage Ui of 1000 V, suitable for low-voltage distribution systems installed within the limits defined by Schneider Electric.

It also has a rated impulse withstand voltage Uimp of 12 kV with pollution degree 3, providing insulation capability against transient overvoltages within the conditions established by the relevant standards.

Cross section of 32.5 x 42.5 mm

The Linergy LGY profile has cross-sectional dimensions of 32.5 x 42.5 mm. Its specific geometry is part of the Linergy design and should not be confused with a conventional flat bar.

Schneider Electric uses an exclusive profile that combines electrical conductivity, mechanical strength, and multiple connection possibilities within tested busbar configurations.

Connection via T-slot

The LVS04505 incorporates a single T-slot connection system. This geometry allows compatible Linergy system components to be fixed to the profile without relying on a single predetermined connection position.

Schneider Electric specifies a free connection position, providing flexibility to distribute connections along the busbar according to the switchboard architecture.

Linergy system for power distribution

Schneider Electric's Linergy range brings together different solutions for distribution and connection inside electrical switchboards. The LVS04505 profile is part of the vertical busbar system and can be combined with the supports and accessories provided by the manufacturer to create a power distribution system adapted to the project.

Using components from the same system makes it easier to design switchboards following Schneider Electric verified configurations and helps maintain consistency between busbars, supports, connections, and enclosures.

IEC 61439-1 and IEC 61439-2 standards

The profile is specified in accordance with IEC 61439-1 and IEC 61439-2, relating to low-voltage switchgear assemblies and power distribution boards.

The final performance of the assembly depends on the complete switchboard configuration, including the number and position of supports, profile arrangement, connections, enclosure, temperature, and other elements covered by the verified design.

ASTA certification

Schneider Electric indicates ASTA certification for this product. The tests and certifications associated with the system help support the declared performance within the specified mounting configurations.

Weight and finish

The profile has a net weight of approximately 3.38 kg and a natural finish. It is supplied as one unit per set.

Due to its 1,670 mm length, care must be taken during transport, handling, and installation to avoid any deformation of the profile that could later affect the correct installation of the busbar or its connections.

Applications of the Linergy LGY LVS04505 profile

This profile is especially suitable for building busbars in high-current low-voltage distribution boards, including:

• PrismaSeT P electrical switchboards.
• Main low-voltage switchboards.
• Industrial electrical distribution systems.
• High-power tertiary installations.
• Commercial buildings and large installations.
