In the realm of electrical distribution, a transformative solution has emerged – the electrical busbar system. These modular systems, often simply referred to as busbar systems, have redefined electrical wiring. Instead of the traditional method of individual cable wiring to each electrical device, these innovative systems mount electrical devices directly onto adapters fitted to a current-carrying busbar.
As highlighted by the International Electrotechnical Commission (IEC) 61439-1, electrical busbar systems adhere to strict safety standards for design and installation. These standards ensure the systems’ reliability and safety, making them ideal for various applications, including distribution boards, automation panels, and other electrical enclosures.
A typical busbar system comprises various components, such as busbar holders, busbars, device-mounting adapters, clamps (with or without protective coverings) for distributing current from the busbar system, and busbar-mountable electrical devices.
One of the key features that sets different busbar systems apart is the distance between the centers of each busbar, which correlates with the maximum current-carrying capacity of the system. These variations are in accordance with IEC standards and include:
- 40 mm Busbar System: Designed for a current-carrying capacity of up to 300–400 Amps.
- 60 mm Busbar System: Capable of handling current loads of up to 800–2500 Amps.
- 100 mm Busbar System: Designed for a current-carrying capacity of up to 1250 Amps.
- 185 mm Busbar System: Capable of handling current loads of up to 2500 Amps.
These systems have the potential to streamline power distribution in various industries, improving efficiency and safety.
