Why Choose the Wöhner 32771 Busbar Adapter?
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.
