About Wohner
Wohner Power Distribution Solutions
Wohner, founded in 1929 and headquartered in Germany, is a leading manufacturer of innovative busbar systems and power-distribution components for electrical enclosures and distribution boards serving industrial, commercial and utility applications in 80+ countries. The company specializes in modular, touch-safe distribution solutions engineered to simplify installation, enhance safety and optimize space efficiency in control panels, switchgear assemblies and power-distribution centers.
The Wohner product portfolio includes several standardized busbar system platforms: System CrossBoard (3-pole touch-safe protected distribution, compact footprint), System 30Compact (3- and 5-pole, rated up to 125 A), System 60Classic (60 mm 3- and 4-pole busbars rated up to 2500 A), and System 185Power (185 mm heavy-duty 3-pole busbar rated up to 2100 A for substations and industrial plants). Each system supports modular assembly with snap-on fuse holders, terminal blocks, adapters and distribution blocks.
Complementary components include dedicated fuse holders (NH, BS, DIN rail versions), terminal blocks for branch distribution, surge-protection modules, power-monitoring devices and support hardware (insulators, adapters, connecting hardware). All products are engineered to international electrical standards (IEC 60947-1, EN 61947) with IP ratings and mechanical ratings matched to enclosure types and environmental conditions.
System selection depends on load current, number of distribution branches and space constraints: CrossBoard and 30Compact serve small control panels and branch circuits; 60Classic handles main distribution in medium-to-large industrial panels; 185Power addresses utility-scale and high-current industrial substations. Wohner provides comprehensive engineering documentation, load-rating tables and schematic symbols to simplify panel design and certification.
ChatMRO accelerates busbar system sourcing by letting you specify required current capacity, pole count, space constraints and modular component requirements, and instantly matching available Wohner systems, adapters and accessories with technical specifications, pricing and delivery status — eliminating manual cross-reference lookups.

Frequently asked questions
What's the difference between the System 60Classic and System 185Power busbar systems?
System 60Classic uses 60 mm busbar width rated up to 2500 A and fits standard industrial electrical enclosures; System 185Power uses 185 mm busbar width for utility-scale applications and power plants, rated up to 2100 A but with much larger physical footprint. Choose 60Classic for most industrial and commercial control panels; choose 185Power for substations, large industrial installations or where extremely high current capacity is needed without parallel busbars.
Are Wohner busbar systems modular, and can I add fuse branches or terminal blocks after initial installation?
Yes — Wohner systems are fully modular; components like fuse holders and terminal blocks snap onto the busbar frame using standardized adapters. You can add, remove or reconfigure branches during installation or later for circuit changes without requiring complete system replacement. This modularity saves design time, reduces panel inventory and simplifies future upgrades.
What does 'touch-safe' mean on Wohner's CrossBoard system?
Touch-safe busbar systems have insulated covers or recessed busbar geometry that prevents accidental finger or tool contact with live electrical conductors, meeting safety requirements for panels in accessible locations. CrossBoard is explicitly designed for environments where panel doors may be opened during operation or maintenance; traditional exposed busbar systems require interlocked enclosure doors or restricted-access cabinet designs.
How do I select the correct fuse holder type (NH, DIN rail, or other) for my Wohner busbar system?
Fuse holder selection depends on fuse type (NH gG semiconductor fuses, BS fuses, DIN rail miniature circuit breakers) and your electrical standards (IEC, DIN or EN). Wohner systems support multiple fuse holder types through snap-on adapter kits matched to each system platform; verify your fuse rating and electrical code requirements, then select the adapter kit matching both your busbar system and fuse type from Wohner's modular component catalog.
Can Wohner busbar systems be installed in outdoor or hazardous (explosive atmosphere) environments?
Standard Wohner systems are rated for indoor industrial enclosures; specialized versions with higher IP ratings (IP66 or higher) and explosive-atmosphere certification (ATEX, IECEx) are available for outdoor or Zone 1/Zone 2 classified locations. Always specify environmental conditions (temperature, humidity, chemical exposure, explosive gases/dusts) during system selection; Wohner can provide certified variants or specialized enclosure solutions.
