Why Choose the Wöhner 01141 Busbar Connecting Terminal?
The Wöhner 01141 is a robust 630 A busbar connecting terminal designed to join matching copper busbars across adjacent sections of industrial switchboards and electrical distribution assemblies. As part of the proven Wöhner 60Classic system, it provides a secure field-to-field connection while maintaining efficient current transmission between busbar sections.
Engineered for professional panel building and power distribution applications, the terminal accommodates busbars with widths of 20, 25 or 30 mm and thicknesses of 5 or 10 mm. Its screw-clamp connection creates a dependable mechanical and electrical joint without requiring holes to be drilled into the busbars.
The Wöhner 01141 has an IEC current capacity of up to 630 A, an IEC rated voltage of 690 V AC and a maximum UL rated current of 756 A. Its compact 95 mm design can bridge system spacing of approximately 50–60 mm, making it ideal for connecting neighbouring distribution fields in modular switchgear installations.

Reliable Connections Between Busbar Sections
Busbar connecting terminals provide a secure electrical bridge between separate busbar sections installed in neighbouring switchboard fields. They help maintain a continuous low-resistance current path while allowing modular electrical cabinets and distribution systems to be assembled, expanded or serviced efficiently.
The Wöhner 01141 uses an M10 screw-clamp connection to hold matching busbars securely in position. Three individual terminals are required for a typical three-pole connection, and the maximum permitted offset between the joined busbars is 5 mm. For UL-compliant applications above 250 V, the appropriate Wöhner separator set should be incorporated into the assembly.
Typical Applications
- Industrial switchboards and electrical distribution panels.
- Connections between neighbouring switchgear fields.
- Motor control centres and automation cabinets.
- Machine power distribution systems.
- Modular low-voltage switchgear assemblies.
- Wöhner 60Classic busbar installations.
