The Guiding System, the new way to create your electrical installations

A comprehensive offer of products with consistent design The Guiding System is first and foremost a Merlin Gerin product offer covering all electrical distribution needs. However, what makes all the difference is that these products have been designed to operate together: mechanical and electrical compatibility, interoperability, modularity, communication. Thus the electrical installation is both optimised and more efficient: better continuity of supply, enhanced safety for people and equipment, guaranteed upgradeability, effective monitoring and control. Tools to simplify design and implementation With the Guiding System, you have a comprehensive range of tools - the Guiding Tools - that will help you increase your product knowledge and product utilisation. Of course this is in compliance with current standards and procedures. These tools include technical booklets and guides, design aid software, training courses, etc. and are regularly updated.

For a genuine partnership with you Because each electrical installation is unique, there is no standard solution. With the Guiding System, the variety of combinations allows for genuine customisation solutions. You can create and implement electrical installations to meet your creative requirements and design knowledge. You and Merlin Gerin's Guiding System form a genuine partnership.

A consistent design of offers from Medium Voltage to Ultra terminal

All Merlin Gerin offers are designed according to electrical, mechanical and communication consistency rules. The products express this consistency by their overall design and shared ergonomics.

Electrical consistency: Each product complies with or enhances system performance at coordination level: breaking capacity, Isc, temperature rise, etc. for more safety, continuity of supply (discrimination) or economic optimisation (cascading). The leading edge technologies employed in Merlin Gerin's Guiding System ensure high performance levels in discrimination and cascading of protection devices, electrodynamic withstand of switches and current distributors, heat loss of devices, distribution blocks and enclosures. Likewise, inter-product ElectroMagnetic Compatibilty (EMC) is guaranteed.

Discrimination guarantees co-ordination between the operating characteristics of serial-connected circuit-breakers. Should a fault occurs downstream, only the circuit-breaker placed immediately upstream from the fault will trip.

Mechanical consistency: Each product adopts dimensional standards simplifying and optimising its use within the system. It shares the same accessories and auxiliaries and complies with global ergonomic choices (utilisation mode, operating mode, setting and configuration devices, tools, etc.) making its installation and operation within the system a simpler process.

Prefabricated and tested solutions, upstream and downstream from the device complying with the IEC 60439-1 switchboard standard.

Communication consistency:

Thanks to the use of standard Web technologies, you can offer your customers intelligent Merlin Gerin switchboards allowing easy access to information: follow-up of currents, voltages, powers, consumption history, etc.

Each product complies with global choices in terms of communication protocols (Modbus, Ethernet, etc.) for simplified integration in the management, supervision and monitoring systems.

Source-changeover systems

E32454

p. 76 (see also the "Source-changeover systems" catalogue)

To ensure a continuous supply of power, some electrical installations are connected to two power sources: b a normal source b a replacement source on hand to supply the installation when the normal source is not available. A mechanical and/or electrical interlocking system between two Interpact, Compact or Masterpact devices avoids all risk of parallel connection of the sources during switching. A source-changeover system can be: b manual with mechanical interlocking between the devices b remote operated when an electrical interlocking function in added b automatic when a controller is added to manage switching from one source to the other on the basis of external parameters.

...optimised protection and accurate measurements

Each Compact NS circuit breaker provides different types of protection, depending on the trip unit or control unit selected. Additional measurement and indication functions are available: b on Compact NS100 to 630, by adding an electrical auxiliary to the circuit breaker b on Compact NS630b to 3200, depending on the Micrologic control unit selected.

Compact NS100 to 630

On Compact NS100 to NS250 circuit breakers, the thermal-magnetic and electronic trip units are interchangeable and may be rapidly fitted to the circuit breakers. It is therefore easy to change the protection of a given circuit following a modification in an installation. On Compact NS400 and NS630 circuit breakers, the electronic trip units are interchangeable, plug-in modules. The STR53UE trip unit offers a large number of protection settings: standard: b specific indication of the different types of faults (overloads, short-circuits, etc.) optional: b built-in ammeter b earth-fault protection b communication: transmission of all information concerning circuit-breaker operation to an electrical distribution control, monitoring and automation system (see page 74).
