Why Choose the Wöhner 32457 Busbar Adapter?
The Wöhner 32457 is a versatile 63 A busbar adapter designed for mounting motor starter combinations and other electrical equipment directly onto industrial busbar systems. As part of the established Wöhner EQUES® 60Classic range, it provides panel builders, switchgear manufacturers and automation engineers with a secure and space-efficient connection between electrical devices and the power distribution system.
This three-pole adapter features a 72 mm-wide adjustable mounting rail and pre-fitted AWG 8 connection leads, helping reduce installation time and minimise conventional panel wiring. Its click-on attachment mechanism enables straightforward mounting, while the adjustable rail supports the installation of motor protection devices, contactors and complete motor starter assemblies from various manufacturers.
With a rated current of 63 A and a rated operating voltage of 690 V AC, the Wöhner 32457 is suitable for demanding industrial power distribution applications. Its compatibility with multiple busbar dimensions makes it a practical choice for control cabinets, motor control centres, machine-building projects and low-voltage switchgear assemblies.

Efficient Mounting for Motor Starter Combinations
The Wöhner 32457 enables motor protection switches, contactors and related control components to be assembled as complete motor starter combinations directly on the busbar system. This approach reduces conventional point-to-point wiring, saves valuable cabinet space and helps create an organised electrical installation.
Its adjustable mounting rail accommodates equipment from different manufacturers, while the pre-installed conductors simplify connection to the mounted devices. A minimum clearance of approximately 12 mm should be maintained above the adapter so that it can be removed safely from the busbar system when servicing is required.
Typical Applications
- Motor starter and motor protection assemblies.
- Industrial control panels and switchboards.
- Motor control centres (MCCs).
- Machine-building and OEM automation systems.
- Low-voltage power distribution equipment.
- Manufacturing and process control installations.
