The Wöhner 32660 is a robust 144 A, 3-pole busbar adapter from the proven Wöhner EQUES® 60Classic range. Specifically designed for mounting Siemens 3VA10 and 3VA11 moulded case circuit breakers (MCCBs) directly onto Wöhner busbar systems, it provides a compact, reliable and efficient solution for industrial power distribution panels.
The adapter features a top system connection, allowing rapid installation whilst significantly reducing conventional wiring. Designed for compatibility with a wide range of flat and section busbars, it enables panel builders to create organised switchboards with improved installation efficiency and simplified maintenance.
With a 144 A IEC rated current, a 690 V AC rated operating voltage and compliance with IEC 61439-1:2020, the Wöhner 32660 is an ideal solution for OEM machinery, industrial control panels, motor control centres and commercial power distribution systems.
The Wöhner 32660 allows Siemens 3VA10 and 3VA11 moulded case circuit breakers to be mounted directly onto the 60Classic busbar system, reducing panel wiring and creating compact, organised switchboard layouts. Direct busbar mounting improves installation efficiency while simplifying maintenance and future modifications.
Its robust mechanical construction and high electrical ratings make the adapter suitable for demanding industrial applications where dependable power distribution and reliable circuit protection are essential. A minimum clearance of 10 mm above the adapter should be provided to allow removal from the busbar system.
