8LS.750 Distribution Busbar Clamp
8LS.750 Distribution Busbar Clamp
For vertical busbar fixing in drawout switchgear drawers
The distribution bar clamp (busbar clamp) is used together with the distribution bar clamp cover and support posts to securely fix vertical busbars inside drawout switchgear drawers. Manufactured from flame‑retardant nylon PA66, it offers excellent mechanical strength, heat resistance, and self‑extinguishing properties, ensuring safe operation and preventing fire propagation in the event of an electrical fault.
Available in two phase spacing options – 55 mm and 50 mm – to accommodate different busbar configurations.
