Automatic circuit breaker of differential current "RCDO-ELTA-2D"

The main advantage of the "RCD-ELTA-2D" over conventional protective disconnection devices is the ability to detect arising sparks on the section of the protected circuit, minimising possible ignition with subsequent fire in case of faulty wiring. The device determines the cause of tripping: critical differential current, over-voltage, arc fault or self-diagnostic error. The use of this device in aluminium alloy wiring reduces the risk of possible accidents resulting from loosening of aluminium wire connections during operation.
