Special features
  • IEC/EN 60947-2 with characteristic conforming to IEC/EN 60947-4-1 with phase failure sensitivity
  • The circuit-breaker fulfills all requirements for AC-3 switching category.
  • R.m.s. value measurement and “thermal memory”
  • Adjustable time delay setting to overcome current peaks tr at 6 x Ir also infinity (without overload releases)
  • All AC-3 rating data applies to direct switching by the circuit-breaker under normal operating conditions. If, for example, a contactor takes over AC-3 switching under normal operating conditions, the full rated uninterrupted current applies to the circuit-breaker, In = Iu.
  • 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: 350 A
  • Terminal capacity hint: Up to 240 mm² can be connected depending on the cable manufacturer.
Fitted with:
Thermal protection
