Air circuit breakers Special versions Series MEGT07 0V/500V/DC 50 up to 5000 A The air circuit breakers MEGT07 are suitable for use as disconnecting switch in DC distributions up to a rated voltage of DC 0V (single pole breaking) and DC 500V (two pole breaking in series). For these applications the standard 3pole types MET07H are provided with modified heightened arc chutes to cover the requirements. For accessories e.g. motordrives, auxiliary trips please refer to pages.57. Series MEGT07 Conformity The disconnecting switch MEGT07 comply with the standard Lowvoltage switchgear and control gear VDE 0660 Part 07, respectively IEC 93. Installation Terminations are rear side suitable only for horizontal plane. The circuit breaker can be mounted on the base without additional parts. A withdrawable version is not available. Power supply 0V: upper terminals / 500V: either on upper or lower terminals. The disconnecting switch must be connected in the DC network as shown in the diagrams below. + + +() (+) 0 V 0 V 500V Single pole breaking () Single pole breaking Single pole breaking for MEG 37/0 Two poles in series and 5007/ Technical data 0 0 Series MEGT 57 07 37 37/0 5007/ Rated insulation voltage Ui DC 500V Rated impulse withstand voltage Uimp 8kV Pollution degree 3 Rated voltage Ue Up to DC 500V DC 0V () Ie Fixed Pollution degree IP00 Temperature For use in enclosures with interior C (A) 50 00 5000 temperatures of to 60ºC C (A) 50 980 5000 the relevant IP00 values can be applied 50 C (A) 50 9 5000 basically.
