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.
Key Advantages
- High-current 1250 A IEC-rated busbar adapter.
- Compatible with selected ABB and Siemens 1250 A circuit breakers.
- Top clamp connection supports fast, drill-free mounting.
- Suitable for six commonly used flat-busbar widths.
- Supports compact and orderly switchboard construction.
- Compliant with IEC 61439-1:2020 and UL 508.
- Halogen-free construction for improved material safety.
- Allows compatible current transformers to be integrated into the assembly.
Key Features
- Wöhner EQUES 185Power busbar adapter.
- 1250 A IEC rated current.
- 1200 A UL rated current.
- Designed for ABB Tmax T7, XT7 and Emax E1.2 circuit breakers.
- Also compatible with Siemens 3VA27 circuit breakers.
- Top-mounted clamp-contact connection.
- Suitable for 185 mm busbar systems.
- Compatible with 30, 40, 60, 80, 100 and 120 mm-wide busbars.
- Three-pole industrial construction.
- Current-transformer integration supported.
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.
Typical Applications
- Industrial low-voltage switchboards.
- Main power-distribution panels.
- ABB Tmax T7 and XT7 circuit-breaker installations.
- ABB Emax E1.2 circuit-breaker installations.
- Siemens 3VA27 circuit-breaker installations.
- OEM machinery and process equipment.
- High-current feeder circuits.
- Energy-monitoring and metering assemblies.
- Commercial and industrial infrastructure.
