Faixa de temperatura ambiente:
Blitzdutor series BXT is limited only by the
-40 °C ≤ Ta ≤ +55 °C – para T6
overvoltage protection. For Blitzductor
-40 °C ≤ Ta ≤ +75 °C – para T5 BXT series type BXT ML2 BD S EX 24, the
-40 °C ≤ Ta ≤ +80 °C – para T4
terminals X3, X4, X3' and X4' are
considered to be connected to earth.
