Busbar Trunking System (BBT)

SANDWICH TYPE BBT (EX)

The compact system EX line is used for the distribution of power in large industries, for riser end feed units, and for commercial and service sector buildings (banks, hospitals, trade, and business centers, etc.). The ultra-compact dimensions of the EX enhance the short-circuit stress resistance features, reduce the impedance of the circuit by limiting voltage drops and enables the installation of high power electrical systems even in extremely cramped spaces. Any section can be taken out without moving the adjacent ones. At any moment it is possible to modify the path of the run, which makes EX a very flexible system. Energypac EX can be installed quickly. It is easy to manage and suitable for modifications and extensions, which is always necessary for installations where EX is used. EX has a wide range of tap-off boxes rated from 25A to 1250A, thus allowing the supply and protection of all kinds of loads due to the availability of different protection devices such as fuses, moulded case circuit breakers, and motorized switches.

Complies with international and domestic standards.
Complies with IEC61439-1 e IEC61439-6.

AIR INSULATED TYPE BBT (AX)

AX (Medium Rating – Air Insulated) is part of the Energypac range used for the distribution of power in medium-large installations; it is also particularly suitable in rising main applications (trunking systems) within buildings used for the service sector. Very compact size, high short circuit strength, low voltage drop, and good corrosion strength make the AX system suitable for installation in small spaces and difficult environments. Any section can be taken out without moving the adjacent ones. At any moment it is possible to modify the path of the run, which makes AX a very flexible system. Energypac AX can be installed quickly also thanks to the single-bolt joint. It is easy to manage and suitable for modifications and extensions, which is always necessary for installations where AX is used. AX has a wide range of tap-off boxes which are rated from 16A to 160A, thus allowing the supply and protection of all kinds of loads using different protection devices such as miniature circuit breakers and/or molded case circuit breakers.

Complies with international and domestic standards.
