KETO - one system, five sizes

With the only 53 mm slim NH fuse-switch disconnector, KETO is now complete.
The small overall width allows two KETO-000s to be arranged exactly in the same place as one KETO-00. Due to the 195 mm field cut-out, no additional accessories are required in most applications. Of course KETO-000 is compatible with all other KETO-00 devices. KETO family can
be combined. In terms of safety, KETO-000 scores highly with its wrap-around and overlap protection, which prevents live parts from being touched during operation. Mounting and contacting on the 5 mm or 10 mm thick busbar is carried out with a single screw connection and a single
connection as in the larger brother KETO-00 saves valuable assembly time.

NH strip-type fuse-switch-disconnectors

Safety, reliability, performance and flexibility are the characteristics associated with NH fuse-switch-disconnectors from JEAN MÜLLER.

Our NH strip-type fuse-switch-disconnectors satisfy all the requirements of power grid operators and industry for power distribution in grid and transformer stations, cable distribution cabinets and low-voltage distribution boards. NH strip-type fuse-switch-disconnectors for converter installation form the basis of efficient energy management.

NH strip-type fuse-switch-disconnectors
The advantages at a glance:

• High load and short-circuit making capacity thanks to controlled arc guidance
• Constant touch protection for contacts enables safe installation of a live system
• Can be combined with measuring and monitoring components for SMART GRID applications

The traditional fuses that we started with over 100 years ago are still part of our product range today. Based on our unique experience, we have further developed products right down to fuses for demanding special applications, such as photovoltaic systems, for example.

While the maintenance-free fuse always limits the impact on systems and components if a short-circuit occurs, special applications require specific solutions. Here, fuses for safe work and semiconductor protection must break fault currents especially quickly, fuses to protect transformers are adapted to individual requirements and photovoltaic systems bring completely different challenges. As well as handling high DC voltages, our fuses have been optimised for the narrow band between the permitted operating current and typically low short-circuit currents.

In conjunction with our NH fuse-bases, the D and D0 fuse range and our HH fuse-links from the IKUS series, our products always bring you peace of mind.

The advantages at a glance:

• NH fuses for a broad range of applications
• Highly specialised fuse-links for protecting semiconductor devices
• Fuses for photovoltaic systems (protecting your investment)
• NH fuse-bases in various sizes (directly mounted or on busbars)
• D-type fuse-links with high switching capacity (can be used by lay people)
• High-voltage, high-performance fuse-links for protecting transformers

Here at JEAN MÜLLER, we aim to provide perfect solutions for switchgear and we do this with a range of components that offer you problem-free technology, new options and simple handling.

From a compact design to integrated electronics, from our rail-mounted bus connectors for simple connection to our carefully developed patch technology, which enables you to start up the system immediately simply by inserting a cable – various features make handling easier for you. All the integrated measuring instruments store the required data, which you can then read out and analyse at your leisure.

Our systems are designed to be put into service quickly and easily. But our expert engineers are of course at your disposal, if you need help with more extensive parameterisation or analysis.

And if you require even more service, we will happily set up our software on your system in such a way that you can visualise precisely the details that are important to you.

The advantages at a glance:

• Disconnectors, strips or SASIL - we offer perfect solutions for switchgear
• Compact design
• Integrated electronics
• Problem-free connection thanks to rail-mounted bus connectors
• Fast, error-free cabling using patch technology
• Storage of data
• Automatic system configuration (PLVario)
• Modular system with minimal installation effort
• System-specific software programming

The enclosure and distribution board product range includes service entrance boxes, service entrance pillars, small distribution pillars and standard cable distribution cabinets – plus low-voltage distribution boards.

The enclosures are available both empty for customers to install their own equipment, or equipped and ready for connection, in the form of distribution cabinets or switchgear combinations. This way, we can offer our customers very special advantages: we design and produce enclosures, switchgear and fuse links ourselves according to the most stringent quality standards.

The result is virtually a complete package, which combines high-tech standards to create solutions with the maximum degree of individuality. All produced from a single source to work in perfect harmony.

So wherever the drill holes are, whichever components need to be combined – we can take care of the job, from advising you to providing you with the best possible solution.

The advantages at a glance:

• Enclosures, switchgear and fuses all work in perfect harmony
• Components designed and produced in-house
• Individual solutions, incl. consulting
• Our distribution and equipment cabinets (DIN EN 60439 – IEC 60439/DIN 43629) satisfy all the requirements of distribution network operators and industry (applications in power distribution and energy usage).
• Sturdy design of cable distribution cabinets
• The upper cabinet and base are combined to form a secure unit with 4 screws

For trade fairs and exhibitions, major events and industrial production – whatever your requirements, SASILplus makes your power supply not only safe but also very easy to implement.

As the strip automatically produces a contact, all you need to do is insert it. No fiddly, millimetre-precise positioning, no fixing with screws – simply attach the strip guides and push SASILplus in like a drawer.

You will also notice the advantages of SASILplus during installation in terms of its weight, as you can quickly integrate or replace the strips in large switch cabinet openings by insertion, even without switching off the voltage.

An intelligent solution which, combined with PLVario, transforms conventional switching technology to achieve state-of-the-art energy data acquisition.

The advantages at a glance:

• User-friendly working
• Faster installation and removal thanks to strip guidance
• High availability
• Interlock function increases safety
• Innovative combination of conventional switching technology and modern energy management
