Now new in the product family:
QUADRON®185Power Speed, switch- disconnector-fuse
The new QUADRON®185Power Speed, switch-disconnector-fuses, in sizes 00 to 3 with an operator-independent snap switching mechanism, now complement the 185Power system. With the new switch-disconnector-fuse, the user also benefits from the numerous advan- tages, with which he is already familiar from the NH in-line fuse switch disconnector: Quick and easy mounting, convenient line terminal, and integrated transformer.
QUADRON®185Power Speed, SWITCH- DISCONNECTOR-FUSE
- Switch-disconnector-fuseproject through the control panel door. This means that operation without opening the control panel door is possible
- Integratable current transformer
- Flag indicator shows the switching state via a red- green field
Multiple possibilities in one system
Mixed installation of switch-disconnector-fuses, switch disconnectors, and circuit breakers, with other components in the same control panel is now possible. With the modular 185Power system, the various components can be combined on a single 185mm busbar system, everything fits perfectly together. You also save space thanks to the narrow width and the gap free mounting of the strips. Even retrofits or extensions to the system are problem-free and possible at any time, thanks to the modular system.
Save space - reduce costs
Low voltage distribution with the 185Power system
The 185Power system lets you implement cost-efficient low voltage distribution systems. The mixed tap-off installation with varying pro- tection on one busbar system in a standard control panel saves space, reducing your overall system costs. The modular design enables order and overview. Even if yet more changes are required to the system at a later date, you are on the safe side with this system 185Power. This lets the user remain flexible, even for future requirements.
Top or bottom connection
Keep your design flexible: With all QUADRON®185Power Speed you can have the cable outlet at the top or the bottom.
The safety plus
Locking and sealing
The QUADRON®185Power Speed, switch-disconnector- fuse can be secured in a number of ways. All strips can be locked with padlocks of up to a maximum of 7mm (NH00) or 8mm (NH1-3) shackle diameter. Unauthorized activation of a strip can effectively be prevented. Seal application provides additional security against
The lock integrated within the switch-disconnector- fuse cover can easily be locked with a control panel key. Thanks to the possibility of access through the closed control panel door, this function secures the QUADRON®185Power Speed against unauthorized opening of the fuse space.
As the snap switching mechanism in combination with the specially designed switching contacts meets the AC-23B utilisation category under the IEC 60947-3 device standard, the QUADRON®185Power Speed, switch-disconnector- fuse are suitable as Supply Circuit Disconnecting Means in accordance with standard IEC 60204-1.Thanks to the AC-23B utilization category, the QUADRON®185Power Speed, switch-disconnector-fuse can also be used for switching of motor and other inductive loads.
Durch die Gebrauchskategorie AC-23A können die QUADRON®185Power Speed, NH-Lasttrennschalter mit Sicherungen in Leistenbauform auch für das Schalten von Motorlasten und anderen induktiven Lasten eingesetzt werden.

Great moments of efficiency
The new NH in-line fuse switch disconnectors
The newly devised, QUADRON®185Power NH in-line fuse switch disconnectors for NH00 to NH3 fuse sizes can be mounted rapidly, easily and securely, in a way that involves no drilling. In a way that involves no drilling. The convenient-to-access line terminal and integration-type transformers (CTs) represent additional highlights of this innovative new family.
Maximum capacity on the bus
The QUADRON®185Power NH in-line fuse switch disconnectors
Easily fit any combination of the QUADRON®185Power NH in-line fuse switch disconnectors of Sizes NH00 to NH3 to the 185Power system. Based on application specific requirements, the NH in-line fuse switch disconnectors can be conveniently, quickly and securely mounted with mechanical clamps without drilling or bolted directly to a drilled busbar.

More variants of the NH in-line fuse switch disconnector QUADRON®185Power
- Size NH00 to NH3 available with electronic fuse monitoring
- Available with LED fuse indicator for indicating the fuse condition
NH in-line fuse switch disconnector, Size NH00
- 3-pole switchable, closed with 3 padlocks, 5mm shackle diameter
- 3-pole switchable, open with 2 padlocks, 5mm shackle diameter
- 1-pole switchable, closed with 1 padlock per lid
NH in-line fuse switch disconnector, Sizes 1-3
- 1- and 3-pole switchable, closed with 3x3 padlocks, 5mm shackle diameter
- 3-pole switchable, open with 3x2 padlocks, 5mm shackle diameter
The lids of the 1-pole switching NH in-line fuse switch disconnectors can be unhinged. A safe parking position is assured from them being turned over and re-mounted. The lid can no longer be inadvertently closed.
Innovative colling and ventilation
Effective discharge of switching gases
The full-length lateral ducts of the QUADRON®185Power NH in-line fuse switch disconnectors produce a kind of draw-off chimney which acts as a cooling and ventilation system for the pinpoint discharging of switching gases and heat. The need for arcing chambers is no longer necessary thanks to this simplified and effective discharge opening method.
Pinpointed diversion of the switching gases for rapidly extinguishing arcs.
Complete flexibility in mounting
One busbar – three connection possibilities
The innovative Wöhner 185Power system opens up a whole new dimension in terms of ease of mounting for switch-disconnector-fuses and NH in-line fuse switch disconnectors. All sizes NH00 to NH1-3 models can be mounted in various ways to the busbar.
Outgoing feeder possible from top or bottom
All NH switch disconnector QUADRON®185Power can be used with the outgoing terminals at the top or bottom. In the NH in-line fuse switch disconnectors, just the base needs to be rotated. The strip housing can be re-ﬁtted in the same position and no change is required to the covering system. In the switch-disconnector-fuses there are two different versions available for top or bottom outgoing terminals.
Easy, safe, efficient: Mounting with mechanical clamp on the CrossLink® touch-safe protections cover
In order to not unnecessarily interrupt the operation of equipment, mechanical clamp-deployed mounting can also be done in an energized state. This ensures maximum safety for a qualified electrician – with due consideration given to BGV A3.
Mounting with M8/M12 bolt connection
Three M8/M12 screws can be used to fix the NH in-line fuse switch disconnector onto either drilled or punched busbars in the traditional method after the added labour of drilling holes in the busbars.
- Contacts are IP10 protected with the lid dismantled
- IP20 touch-safe when completely assembled
Variability in the connection method
Easily accessible terminal compartment
Simple connection increases efficiency. For all switch-disconnector-fuses and NH in-line fuse switch disconnectors, vast importance was placed on an easily accessible terminal compartment. Depending on the type, the cover can be either opened or pushed out and removed – for all connection types.
