1 F Off-Load Switches Up to 8000 and C/DC Expertly engineered for reliable performance

2 For more than years has been providing safe and reliable solutions for switching and disconnecting high power. High Power Switches include different ranges of proven technologies: That gives us worldwilde recognized expertise in Switching and Disconnecting. The silver-platted copper-made mobile contacts are of the wiping (silver to silver) blade type, allowing self-cleaning during operations. They consist of two parallel blades or sets of two parallel blades paralleled each other to achieve higher current ratings (rating > 000 ). Massive silver rivets are inserted on the contact area of the mobile blades to improve current interchange. Stainless steel backup springs, mounted between each blades, assure high pressure contact wiping allowing to achieve maximum pinch performance and so very high electrical withstand, low voltage drop and low temperature rises. F range: C/DC and up to C / 8000 DC F disconnectors and switches offer safety, high performances, reliability and robustness for heavy duty requirements with very limited maintenance. That makes our F range particularly suited to be used in most demanding and critical applications: Power Generation (Hydro, Thermal, Wind, P), DC traction (Metros and Tramways substations, depots), Mining F F1 F switches are available as disconnecting switches (F), two-positions change-over or grounding switches (F1) and three-positions change-over switches with (F) or without (F13) central off-position. F technology is used to isolate a circuit (insulation level as per IEC standard) whereas F1, F13 and F are used to select off-load a circuit ; F has a central offposition. From a modular design F switches are available from 1 up to 6 main poles with a thermal current ranging from C/DC up to 8000 DC ( C). Insulation voltage is C/DC. F 1P 8000-DC Three-positions switches manually operated are equipped with a locking handle allowing to easily select and maintain the switch position.

Manual operation is achieved using a handle which can be directly fixed on the switch or on the panel door of a cubicle using an optional shaft extension (50,0,,00,50 mm). Electrical operation is achieved using a geared motor which can be equipped with an optional hand crank for manual operation (electrical interlocking of the hand crank available under request) Motor operated F 3 Poles 000 Basically a F switch consists in one shaft mounted between two light-alloys flanges. This shaft allows to actuate by the way of insulating-connecting-rods the mobile contacts of the poles (making the break easily visible). These poles (up to 6) are assembled between the flanges using polyester insulators insuring the creepage distances and requested insulation level. This design also allows to isolate the live side of the switch from the control side and to operate it safely. The upper and bottom connecting plates allow to easily connect the switch to the supplying bus-bars or cables. Manual operation F1 uxiliary contacts In standard configuration F products can be supplied with two or four auxiliary contacts (1NO + 1NC see characteristics page 5) per position (other optional configurations available under request).

3 Options Technical data F can be provided with a wide range of options such as locking devices, control terminals, control boxes, operations counter, special auxiliary contacts Locking devices Control terminal and Control box Manual switches are lockable in both open and closed position either using a key lock or a padlock. Key locks are mounted on the top and/or the bottom of the handle support. When turning the key the lock-bolt will mechanically lock the handle in position; as an option an auxiliary contact can be used to indicate the status of the locking device.

Key-locks are mounted on the gear motor through a machine-welded support; here the lockbolt will directly act on the driving shaft of the gear-motor making it impossible to rotate. n auxiliary contact can be used to indicate the status (open / closed) of the key-lock. Control terminal and control box are also available as options.
