Characteristics of products
DBL1-40AFD series of arc fault protection device include leakage protection,fault arc protection, overload protection and short circuit protection functions.DBL1-40AFD series of arc fault protection appliances leakage tripping characteristics as shown in Table 1 below:

The arc fault protection function of DBL1-40AFD series of arc fault protection devices mainly includes the arc fault protection detection unit, which detects and identifies the fault arc in the line and sends out the tripping signal. The DBL1-40AFD main contact is automatically converted from the closed position to the disconnected position, thus disconnecting the fault line.
Action judgement and breaking time maximum value of a 230V rated arc fault protection device is shown in Table 2, Table 3.
Table 2 ,maximum value of ADDF action judgment under high arc current below 40A
| Test arc current (Effectiv Value) | 3A | 6A | 13A | 20A | 40A |
| Maximum segmen time | 1S | 0.5S | 0.15S | 0.25S | 0.12S |
Test arc current is the expected current before burning in test circuit.

N is half wave number at rated frequency.
DBL1-40AFD overcurrent protection function of a series of arc fault protection devices. When the circuit current exceeds the rated current of the product,bending deformation occurs DBL1-40AFD the hot stripper system in the series arc fault protection appliances to drive the main contact from the closed position to the disconnected position. Thus disconnecting the current.DBL1-40AFD arc fault protection appliances overcurrent tripping characteristics as shown in Table 4
