Advantages


  • Two types of short circuit and overload protection.
  • Complete set of supplementary devices with the possibility of simple independent installation:
    • Status contact KS47;
    • Status contact KSV47;
    • Undervoltage release RMM47;
    • Shunt trip RN47.
  • Special casing construction with boosted heat dissipation.
  • Independent contact position indicator.
  • DIN rail latch with a double fixed position.
  • Wide range of operating temperatures from –40 to +50° .
  • Updated wider engagement lever with improved contact area.
  • Notches on terminal clamps lower thermal losses and boost the mechanical stability of connection.

Design Features


  Circuit breaker construction provides two types of overload and short circuit protection that can essentially boost the safety of distribution and group systems.   Connecting a bus to the circuit breaker provides for ensuring two or three-wire connection.
  Unified casing with the possibility to connect supplementary devices does not require disassembling. Independent installation is possible.   Main circuit status indicator provides exact information on the contacts status independently from lever position.
  Boosted screw head dimension with cross-functional crest (+,–) helps to facilitate mounting and prevents the screws from falling out during the installation.   Welding deposition of silver-bearing composite boosts the contact block’s wear-resistance and lowers the transient one.
  Plexiglas fitting protects the thermal cut-off mechanism from the factory settings changing.   Updated wider engagement lever with improved contact area facilitates commutation process.
  Special casing construction with boosted heat dissipation allows raising the output capacity per 10%.   Notches on terminal clamps allow lowering thermal losses and boosting the mechanical stability of connection.
