£153.06
The Wöhner 01594, full part number 01594000A, is a three-pole rear-feed connection module for the Wöhner CRITO® CrossBoard® 125 A and 250 A systems. Designed for plug-and-play rear power feeding, it provides a compact, space-saving solution for industrial power distribution whilst allowing electrical and mechanical installation in a single step.
Featuring screw-clamp terminals for conductors up to 150 mm², the module supports both top and bottom cable entry, providing greater flexibility when designing switchboards and control panels. It is suitable for CrossBoard® systems from 300 mm to 1100 mm wide and can also be used for linking multiple CrossBoard assemblies.
With a rated current of 320 A (IEC), compatibility with both copper and aluminium conductors, and compliance with IEC 61439-1, IEC 60999-1, IEC 60999-2 and UL 508, the Wöhner 01594 is an ideal solution for modern industrial and commercial electrical distribution systems.
The Wöhner 01594 enables electrical power to be supplied from the rear of a CrossBoard® assembly, freeing valuable front-panel space for outgoing protection devices. Its plug-and-play concept allows both electrical connection and mechanical fixing in a single installation step, significantly reducing assembly time.
The large terminal capacity supports round conductors up to 150 mm², while compatibility with aluminium conductors provides additional installation flexibility for demanding industrial applications.
