Special features
  • Maximum back-up fuse, if the expected short-circuit currents at the installation location exceed the switching capacity of the circuit breaker (Rated short-circuit breaking capacity Icn)
  • Rated current = rated uninterrupted current: 250 A
  • Switches conform to UL/CSA as well as the IEC regulations. IEC switching performance values are contained on the rating plate.
  • Adjustable overload releases Ir
  • R.m.s. value measurement and “thermal memory”
  • adjustable time delay setting to overcome current peaks tr: 2 – 20 s at 6 x Ir
  • Adjustable delay time tsd: Steps: 0, 20, 60, 100, 200, 300, 500, 750, 1000 ms
  • i²t constant function: fixed OFF
