1) Breaker cannot be used for direct current.
2) Exception: 3VL molded case circuit breaker w
ith TMTU: 0 °C ... 70 °C
3) The values apply for at least 3 current paths in series and extremely high breaking capacity L. For switching direct
current, the maximum permissible direct voltage per current path must be observed.
4) VL160X in the 16 A and 20 A version cannot be used at 690 V.
