The DS-ARC1 is the new 1P+N Arc Fault Detection Device (AFDD) with an integrated residual current
circuit breaker with overcurrent protection (RCBO) in only three module width.
The series offers a complete protection against arc faults and overvoltage, reducing the risk of fire. 3
The integrated RCBO is adding protection against overcurrent and earth fault currents:
compact solution for a complete protection of people and valuable assets.
