Wöhner 01066 three-pole 500 A rear feed connection module for CrossBoard 800 A systems with screw-clamp terminals, top or bottom cable entry and conductor capacity up to 300 mm².
The Wöhner 01066, full part number 01066000A, is a robust three-pole 500 A rear feed connection module designed specifically for the Wöhner CrossBoard® 800 A system. Part of the innovative CRITO® CrossBoard range, it provides a compact and reliable solution for supplying power from the rear of the busbar assembly whilst maximising usable space on the front of the distribution board.
Designed for industrial switchboards, OEM machinery and commercial electrical installations, the module accepts copper conductors up to 300 mm² and supports top or bottom cable entry. This flexible arrangement simplifies cable routing and enables cleaner, more organised panel layouts.
With an IEC rated current of 500 A, a 690 V AC rated operational voltage and compliance with IEC 61439-1, IEC 60999-1, IEC 60999-2 and UL 508, the Wöhner 01066 is ideal for medium to high-current feeder applications requiring dependable rear power entry into CrossBoard® systems.
The Wöhner 01066 allows electrical power to be supplied directly from the rear of a CrossBoard® 800 A assembly, freeing valuable front-panel space for outgoing devices and simplifying switchboard design. The rear-feed arrangement also improves cable management and helps create a cleaner, more accessible installation.
Its heavy-duty screw-clamp terminals provide dependable electrical connections for medium to high-current feeder circuits, making the module ideal for industrial power-distribution applications where reliability and ease of installation are essential.
