The Wöhner 32771 is a high-capacity 1150 A busbar adapter from the Wöhner EQUES 185Power range, designed for mounting a compatible Siemens 3VL7 1250 A moulded case circuit breaker directly onto a 185 mm busbar system. It provides a secure and efficient connection solution for demanding industrial switchgear and low-voltage power distribution assemblies.
Featuring a bottom clamp connection, the adapter enables the circuit breaker to be integrated without drilling the busbars. This modular arrangement helps reduce installation time, conventional cabling and space requirements while providing dependable electrical and mechanical performance in high-current applications.
With an IEC rated current of 1150 A, an operating voltage of up to 690 V AC or 800 V DC and compatibility with busbars from 30 × 10 mm to 120 × 10 mm, the Wöhner 32771 is suitable for industrial distribution boards, motor control centres and other high-performance electrical installations.
Key Advantages
High-capacity 1150 A busbar adapter for demanding power distribution systems.
Designed for the Siemens 3VL7 1250 A circuit breaker.
Compatible with multiple Wöhner 185Power busbar sizes.
Space for integrating up to six compatible current transformers.
High short-circuit withstand capability for industrial switchgear applications.
Key Features
Wöhner EQUES 185Power series.
1150 A IEC rated current.
1200 A UL rated current.
690 V AC and 800 V DC IEC rated voltage.
1000 V AC/DC rated insulation voltage.
12 kV rated impulse withstand voltage.
Three-pole configuration with bottom clamp connection.
Compatible with busbars measuring 30, 40, 60, 80, 100 or 120 × 10 mm.
Reliable High-Current Circuit Breaker Integration
The Wöhner 32771 allows a compatible Siemens 3VL7 circuit breaker to be mounted directly onto the 185Power busbar system. This direct connection arrangement can simplify switchboard construction, reduce cable lengths and create a more organised power distribution assembly.
The adapter also provides sufficient installation space for two sets of three compatible current transformers. This makes it suitable for systems requiring current measurement, energy monitoring or protection functions alongside high-current circuit breaker integration.
