Switching or disconnecting

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
Size 00/185mm

  • Available in two depths
  • 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

QUADRON®185Power Speed, SWITCH- DISCONNECTOR-FUSE
Size 1-3/185mm

  • 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

Operator-independent switching

Regardless of who is moving the lever – the automatic snap switching mechanism of the QUADRON®185Power Speed, switch- disconnector-fuse switches with a defined speed. Danger from arcing is therefore effectively excluded. The snap switching mechanism always disconnects both NH fuse unit contacts from the voltage-carrying components. This double break ensures even more safety.




Mixed Possibilities
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.


Switching even through the control panel door

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.



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

Cover locking

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.


Standard-compliant systems

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.

Parking position

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.

Two QUADRON®185Power NH in-line fuse switch disconnectors fitted next to each other create at their centre a full length ventilation duct which - like a chimney - discharges hot air.

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.



1.

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.



2.

No-drill mounting with a mechanical clamp

Mounting with mechanical clamps to a system without CrossLink touch-safe protections is also possible. In so doing, the strip can be easily attached onto the bus without this added level of protection.


3.

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.


No dismantling - mounting convenience

The NH in-line fuse switch disconnectors can be directly mounted on the busbar through a hinged window – without them having to be dismantled beforehand.

  • 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.


Connection arrangement 1

Box terminal

No additional terminal compartment cover is needed when using a box terminal for the connection.


Connection arrangement 2

Drawer-type method

The drawer-type method allows for a considerable variation in connections. Connection can be flexibly made with either nut or stud bolt – depending on installation requirements. An additional terminal housing cover is needed when using a cable lug for the connection. These covers can be linked in series to form longer covers.

Current transformer mounting
Intelligently solved

Without any extra space required, current tranformers can be easily swung into the strip structure. CTs are available in all standard measuring ranges and precision classes.
