Basic Design The FMX system is modular in construction. This ensures that any panel combination and sequence is possible. In addition, the number of panels capable of being used in an installation is unlimited, as several sections can easily be connected. The panels in the FMX system are compact (min. 500 mm wide), resulting in considerable savings in costs and installation space. Circuit-breaker panel (example) 1. Protection relay 8. Manual operation panel with position indicator 3. Mimic diagram with push buttons for operation of circuit-breaker and twoposition change-over switch 4....

Main Components Vacuum circuit-breaker The vacuum circuit-breaker uses a simple and reliable electromagnetic mechanism for operation of the vacuum interrupters. The construction of the mechanical linkage between the actuator and the drive rod of each of the three vacuum interrupters is reduced in complexity, compared to a conventional spring-charged mechanism. Features • Environmentally friendly vacuum interrupters • Electromagnetic mechanism with controller • Mechanical lever for hand-operated operation (switch off) • Mechanical position indicator for Open / Closed position • Auxiliary...

Eaton Core Technologies Solid insulation using cast resin technology Epoxy resin (cast resin) is used as high-quality primary solid insulation material around live parts. By using cast resin technology for solid insulation, Eaton design engineers can shape the parts specifically for optimal insulation, robust construction and cooling purposes. With many years of experience of design and manufacture of epoxy resin insulated components, we have learned to integrate conductors and vacuum interrupters directly into the moulding, and to make complex shapes. FMX utilises optimal field control...

Innovative Electromagnetic Mechanism The advantage of an electromagnetic mechanism over a conventional spring operated mechanism To switch a vacuum interrupter effectively, the driving mechanism has to operate according to a specific forcestroke characteristic (-), see the diagram. Force-stroke characteristics - as required by vacuum switch - as offered by a conventional spring operated mechanism Stroke (mm) A conventional, spring operated mechanism has force-stroke characteristics (-) that differ greatly from the required characteristics. The required force-stroke diagram therefore has to...

Reliable and Safe in Operation Eaton's proven technologies have been integrated in the design and development of the FMX in order to ensure that the switchgear is safe and has high operational reliability throughout its complete lifetime. Experience and knowledge gained over many years in the areas of cast resin technology, vacuum technology and electrical field control have been implemented. The system has been thoroughly arc fault tested according to the latest standard IEC 62271-200. Preventing an Internal Arc Within the FMX design, different technologies are used to prevent an internal...

Routine tests Various prescribed routine tests are carried out during the production of the switchgear. To assure quality, all processes are in accordance with DIN EN 9001. This means that at every stage of production the components, circuit-breakers and current transformers are inspected for correct functioning. When the entire installation has been assembled, a thorough visual inspection is carried out, together with mechanical, functional and electrical checks. Philosophy on Internal arcs Eaton always puts extra focus on creating safe switchgear for operators at all times. One of the...
