Derating in accordance with ambient temperature K : Squarre Root ((110 - Ambiant temperature C) / 70) Example of selection : Circuit 500Hz Amp V, single phased, Ambiant temperature 50 C, isolation of go and back ways Solution Derating factor K = Squarre root ((110-50)/70) = 0,92 Therefore the use of device with maximum permissible current of 7200 A/ 0,92 = 7826 Amp is required i.e. : MF200 (1-0) with 6 single sided poles sandwiched RSRSRS, 3 poles for each phase. in mum current per phase of 2650 X 3 = 7950 Amp (higher than 7826 Amp, therefore corrrect) 6

- Devices with 1 isolated pole among 2 to keep the reduction of the electromagnetic influence (proximity effect) in the case the way back must not be isolated.

7 Functions Special types on Request - Liquid cooled device enabling thus the reduction of its dimensions. - Length deformable devices (±15 mm max.). Their use can be a good solution to absorb the elongation due to the dilatation of connected bars (30mm). - For double sided devices, E space of sides shall be from 0 to 20 mm (standard : 10 mm). - Devices with 1 isolated pole among 2 to keep the reduction of the electromagnetic influence (proximity effect) in the case the way back must not be isolated. R S R S R S R S R S R S Isolated to-and-fro movement Non Isolated fro movement Electrical precautions Above 175 Hz, pole must be sandwiched RSRSRS... in single phase circuit or RSTRSTRST... in three phase circuit. In single phase circuit, if we wish to isolate the fro movement of current, one can use devices with 1 not isolated pole among 2. For induction furnace application : When the device is placed on the output of an inverter, the best solution consists in separating the circuits of each pole by allocating the same of capacitors. If it is not possible, make sure that the impedance per pole be slightly equal by adapting symmetrical connecting arrangements. Note : The use of a liquid cooled device often leads to a simpified busbar. Non-Magnetic and Tropicalized version All the MF range is Non-magnetic and tropicalized This range is using stainless steel and a tropicalized version of motor or microswitches and special paints. 7
