Why Choose the Wöhner 32663 Busbar Adapter?
The Wöhner 32663 is a robust 80 A, 3-pole busbar adapter from the Wöhner EQUES® 60Classic range. It has been specifically designed for mounting Siemens SIRIUS frame size S2 direct starters directly onto Wöhner busbar systems, providing a compact, reliable and efficient solution for industrial motor control applications.
Supplied with 260 mm AWG 4 (25 mm²) flying leads, the adapter simplifies wiring to Siemens S2 starters whilst reducing assembly time. Ultrasonically sealed conductor ends improve long-term electrical reliability, and the integrated click mechanism allows secure installation directly onto the busbar without additional mounting hardware.
Rated at 80 A with a 690 V AC operating voltage, the Wöhner 32663 complies with IEC 61439-1:2020 and UL 508, making it an ideal choice for OEM machinery, industrial control panels, motor control centres and low-voltage power distribution systems.
