Why Choose the Wöhner 32765 EQUES 185Power Busbar Adapter?
The Wöhner 32765 is a high-current 1250 A busbar adapter from the Wöhner EQUES 185Power range. It is designed for mounting compatible ABB Tmax T7, ABB XT7, ABB Emax E1.2 and Siemens 3VA27 circuit breakers directly onto an industrial busbar system with 185 mm busbar spacing.
Featuring a top clamp connection, the adapter creates a reliable mechanical and electrical interface without requiring the busbars to be drilled. This can reduce assembly work, minimise conventional cabling and help panel builders create compact, clearly organised low-voltage distribution assemblies.
The Wöhner 32765 measures 300 × 652 × 85 mm and accommodates flat copper busbars from 30 × 10 mm to 120 × 10 mm. It is rated at 1250 A under IEC conditions and 1200 A under UL conditions, making it suitable for demanding feeder and power-distribution applications.

Direct Integration for ABB and Siemens Circuit Breakers
The Wöhner 32765 provides a purpose-designed interface between compatible 1250 A circuit breakers and the 185Power busbar system. Direct busbar mounting can reduce the number of separate conductors, terminals and connection components required within the switchboard, supporting a cleaner and more space-efficient installation.
Its clamp-contact technology secures the adapter to compatible flat busbars without drilling. This helps simplify initial assembly and can make future system modifications more straightforward. The adapter also supports the integration of current transformers, making it suitable for installations requiring metering, monitoring or energy-management functions.
The short-circuit capability of the completed adapter and circuit-breaker combination depends on the characteristics and ratings of the installed circuit breaker. Device compatibility, system design and installation requirements should therefore be verified before commissioning.
