|FA142022||Will Tesys U be de rated with altitude? How will the de rating happens?|
With higher altitudes, Tesys U will be capable of being used on lower voltages (Ue) and capable of switching lower amperages than the nominal (In).
|FA142123||What’s the heat dissipation on the LRD range of overloads?|
|FA142362||What’s the heat loss (power dissipated) on the GV (GV2, GV3, GV7) range of MCB’s?|
Extracted from the Control and protection components 2011/2012 catalogue MKTED210011EN.
|FA142128||What’s the Earth loop impedance value Zs for the GV3 range?|

|FA142358||Will GV2, GV3 and GV7 get de-rated with altitude? How will the de-rating work?|
Yes, for altitudes higher than 2000 metres, see below the de-rating on this table:
|FA142425||Is there an enclosure for GV3, to make an enclosed starter? Can we fit GV3P, GV3L and GV3ME? Can we mount LC1 contactor?|
Yes, there is an enclosure that can take the new GV3P and GV3L, plus there’s space to mount a contactor inside.
The new enclosures GV3PC aren’t suitable...
|FA142452||What information is required to correctly select (specify) a contactor?|
