Special features
  • LSI overload protection and delayed and non-delayed short-circuit protective device
  • Class 1 energy measurement, r.m.s. value measurement, and "thermal memory"
  • USB interface for configuration and test function with Power Xpert Protection Manager software
  • Interface module in equipment supplied.
  • Optionally communication-capable with internal Modbus RTU module or CAM
  • 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
  • Terminal capacity hint: Up to 240 mm² can be connected depending on the cable manufacturer.
