Phase failure protection (built-in electronic release: operates unbalanced single-phase currentat 40% and more than)(tripping time delay 4s±10%),as defined by IEC60947-4.1 4. Load indication : Flashing more than Ir setting threshold 5. Fault indication LEDs indicates the type of fault that caused tripping Overload (LT protection) or abnormal component temperature (>Ir); Short-circuit (ST or instantaneous protection)( >Im); Phase failure (right LED); Microprocessor malfunction ( (>Ir) ( >Im) and phase failure LEDs all go on ) Battery powered. Spare battery are supplied in an adapter box. When a fault occurs ,the LEDindicating the type of fault ,lights for about 10 minutes. The information is however stored inmemory.The LED can be illuminated by pressing the test pushbutton. The LED automaticallygoes off and the memory is cleared when the circuit breaker is reset.
