Description

  • The ABB 2CSR256140R1257 is a part of the DS203NC series, designed to provide robust protection and security for electrical circuits. This specific product is a 3P+N (three-pole plus neutral) Residual Current Circuit Breaker with Overcurrent Protection (RCBO), offering comprehensive protection against a wide range of electrical hazards commonly encountered in electrical systems.


  • The primary function of the DS203NC RCBO is to deliver comprehensive protection against various electrical faults and hazards. This includes protection against short-circuit currents, overload conditions, earth fault currents, indirect electrical contacts, and additional protection against direct electrical contacts with a sensitivity of 30 mA.


  • Short-circuit protection is a vital feature of this RCBO. It is engineered to rapidly detect and respond to short-circuit conditions, promptly disconnecting the circuit to prevent further damage or hazards. This is essential for safeguarding electrical equipment and preventing safety risks.
