BDM2 23SE: protection of low-voltage distribution networks for BDM2-400630

1. Overload protection with adjustable threshold  2. Short-circuit protection with adjustable threshold 3. Load indication : light at 90% of Ir setting threshold;  Flashing at 105% or more of Ir setting threshold

1. Overload protection with adjustable threshold, as defined by IEC60947-2  2. Short-circuit protection with adjustable threshold  3. Instantaneous short-circuit protection 4. Earth fault protection with adjustable threshold 5. Load indication : light at 90% of Ir setting threshold; Flashing more than Ir setting threshold 6. 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); Earth fault (if earth fault protection option is present)(Ig); Microprocessor malfunction (both (>Ir) and ( >Im) LEDs go on ,plus the (Ig) LEDs if earth fault protection option is present ) Battery powered. Spare battery are supplied in an adapter box. When a fault occurs , the LED indicating the type of fault ,lights for about 10 minutes . The information is however stored in memory . The LED can be illuminated by pressing the test pushbutton. The LED automatically goes off and the memory is cleared when the circuit breaker is reset .
