£28.89
The Wöhner 32439 is a dependable 25 A, 3-pole busbar adapter designed for mounting motor protection switches, circuit breakers and other switching devices directly onto compatible 60 mm busbar systems. Part of the trusted Wöhner EQUES 60Classic range, it provides a compact and flexible solution for industrial switchgear, control panels and OEM machinery.
The adapter features two adjustable mounting rails and rear-mounted screw terminals accepting conductors up to 6 mm², allowing panel builders to use custom cable lengths instead of fixed leads. Its click-fit installation simplifies mounting while providing a secure mechanical connection to compatible flat and section busbars.
Rated at 25 A with an operational voltage of up to 690 V AC, the Wöhner 32439 is ideal for industrial motor control, power distribution and machinery applications requiring reliable, field-wirable busbar mounting. The extended 45 × 260 mm format provides additional mounting height for larger devices.
The Wöhner 32439 enables switching and protection devices to be mounted directly onto compatible busbar systems while allowing installers to use their preferred conductor lengths via the rear screw terminals. This helps reduce unnecessary wiring and supports tidy, serviceable control panel layouts.
Its extended mounting height and adjustable rails make the adapter particularly suitable for larger switching devices, while direct busbar installation improves installation efficiency and makes effective use of available cabinet space.
