Wöhner Vietnam – Solutions for Power Distribution, Protection, Switching and Measurement
Modern electrical systems require much more than the safe distribution of electrical power. Industrial control panels and low-voltage distribution systems are increasingly expected to use installation space efficiently, simplify assembly and maintenance, support modular expansion and provide access to meaningful energy data.
Wöhner is a German electrical engineering company specializing in technologies for the distribution, protection, switching, control and measurement of electrical energy.
Importantly, Wöhner should not be described only as a busbar-system manufacturer. Its current official online catalogue is structured around six major product areas: measurement technology, busbar systems, panel-mounted fuse holders, panel-mounted switching devices, accessories and value-added services.
The brand name Wöhner is also sometimes typed as Woehner or Wohner in online searches when the German character “ö” is not readily available. Wöhner remains the official spelling used throughout this article.
PECS Prime Enclosure and Cooling Solutions Co., Ltd. is an authorized and official distributor of Wöhner in Vietnam, supplying genuine products, providing product and application support and maintaining local stock of commonly used Wöhner products.

2.3 Fuse Holders for Panel or DIN-Rail Installation
Wöhner also has an extensive range of fuse holders that do not require a Wöhner busbar system.
The portfolio includes D0 fuse bases, D fuse bases and NH fuse bases in different sizes and pole configurations.
For IEC/EN applications, Wöhner provides cylindrical fuse holders in sizes including 10×38, 14×51, 22×58 and 10×85, including versions for photovoltaic applications.
For applications based on UL/CSA requirements, Wöhner also offers Class CC holders and Class J fuse bases covering several current ratings.
These products allow Wöhner to support both system-based busbar architectures and conventional panel or DIN-rail installations.
2.4 Switching and Motor-Control Devices
Switching and motor control form another major area of the Wöhner portfolio.
The MOTUS family includes hybrid motor starters, while MOTUS C14 provides an electronic motor-starter platform.
Wöhner also supplies D0 switch-disconnector-fuses, three-pole NH fuse-switch-disconnectors and other NH switching solutions.
For applications where fuse protection is not required within the switch, Wöhner provides switch-disconnectors in several pole configurations and a broad range of rated currents. The current catalogue includes three-pole devices reaching up to 3,150 A.
The portfolio also includes three-pole and three-pole-plus-neutral changeover switches.
This product range allows Wöhner to address not only power distribution but also load isolation, circuit protection, switching and motor-control functions.
2.5 Fuse Links and Accessories
Wöhner's accessory portfolio is extensive and supports both busbar-based and traditional electrical installations.
It includes D0, D and NH fuse links, together with the corresponding gauge elements, screw caps and related accessories.
NH gG fuse links are available for applications at 400/500 V and 690 V.
The IEC/EN cylindrical fuse range includes gG/gL types, aR/gR semiconductor-protection fuses and gPV photovoltaic fuse links.
For UL/CSA-oriented applications, the range also covers Class CC and Class J solutions.
In addition to fuse products, Wöhner offers insulators, laminated flexible copper busbars, holders for flexible copper and connection bars for PE and N conductors.
2.5 Wöhner Product Families
Customers will also frequently encounter Wöhner product-family names such as CRITO, EQUES, QUADRON, SECUR, MOTUS, OMUS and BROOME.
These names should not be confused with the basic busbar-system categories.
- CRITO represents connection technology, while EQUES is associated with device-adapter solutions.
- QUADRON is used for NH fuse-switching and fuse-protection solutions.
- SECUR covers fused switching solutions.
- MOTUS is Wöhner's motor-starter family.
