Residual current circuit breaker DVA-10 1P+N 40A characteristic B 300mA type A electromechanical 10kA AVERES EKF rcbo10-1pn-40b-300-a-av

DVA-6 and DVA-10 series AVERES residual current circuit breakers (RCCB) are used in AC electrical circuits with a rated voltage of 230 V / 400 V and a frequency of 50 / 60 Hz. Designed for: • protection of people from electric shock upon accidental contact with live parts of electrical installations; • protection of electrical equipment against insulation damage and faults; • prevention of fires caused by leakage currents and resulting short circuits, ground faults, and earth faults; • automatic disconnection of a section of the electrical network during overloads and short circuits.
