Residual Current Breake Operator DPNL

AFDD RCBO DPNL DGB3LE-40AFD

DGB3LE-40AFD
DGB3LE-40AFD series of arc fault protection derivces are assembled by small circuit breaker, tripping mechanism, leakage and arc detection module.DGB3- 40AFD series of arc fault protection devices have the functions of short circuit protection, overload protection, leakage protection and arc fault protection. It detects the current of zero sequence current transformer through chip detection program, realizes the function of leakage protection, and detects arc fault through chip detection program, that is, it will disconnect power supply and play the role of arc fault protection. According to the China Fire Yearbook, the proportion of electric fire in the total fire is increasing year by year. However, 70% of the electric fire is caused by fault electricity, DGB3-40AFD series of arc fault protection devices can effectively avoid the fire caused by arc fault.

The arc fault protection function of DGB3LE-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 DGB3LE-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 Table2,Table 3.
