Digital Electric Systems offer standard Pre-assembled Busbar Pan Assemblies for Low Voltage SMDBs that are designed, manufactured and type tested as per the latest edition of IEC 61439 standards. The Pan Assemblies can be utilized by Panel builders to incorporate in their SMDBs or other Panel systems. This offers them a technically superior, at the same time a cost-effective solution to accommodate circuit breakers from various reputed manufacturers. It adopts a simplified, safe and sturdy construction concept that is modular, ensuring a busbar system that is quality tested and proven with decades of experience in the middle eastern market.

DES Busbar Pan Assemblies are equipped with a Moulded and Encapsulated Pan Assembly structure that will be fully segregated from functional units and cable compartments. The moulded insulating material is made of a special grade glass reinforced polyamide having a continuous operating temperature rating of 140°C and Glow wire performance of 960°C.
The Fully Moulded busbar system with inter-phase barriers prevents the possibility of internal circuit faults within the assembly.
Ready to Install purpose fitted mounting brackets are provided as an option, to easily install Incoming devices and Outgoing devices (MCCBs).
The top cover can be opened for easy inspection of joints and to perform Dielectric tests.
Designed to withstand Harsh Environments – use of Tin-plated copper busbars and the fully moulded casing for the busbar pan assembly ensures protection against corrosion, oxidization, etc.
Copper: Tin Plated, HDHC, 99.9% Purity, ETP Grade used for main busbar and interconnections.
