STTB 2,5-PE/L - Protective conductor double-level terminal block

Protective conductor double-level terminal block, nom. voltage: 500 V, nominal current: 22 A, connection method: Spring-cage connection, 1st and 2nd level, Rated cross section: 2.5 mm2, cross section: 0.08 mm2 - 4 mm2, mounting type: NS 35/7,5, NS 35/15, color: gray-yellow-green

  • The color coding of the PE and N levels helps to create clear and unambiguous potential distribution
  • These mixed versions combine the advantages of double-level feed-through terminal blocks and ground terminal blocks of the same shape
  • The PE/L and PE/N types feature a protective conductor contact with the DIN rail in the lower level, while the upper level is designed as a feed-through level
  • Potential routing on two levels
