Combined circuit with an electronic module of differential protection, D-class varistor and integrated circuit breaker of DAB7-63 series ensures 4 types of protection: from residual current (leakage current), short circuit; overload and surge overvoltage. |
Welding deposition of silver-bearing composite provides for boosting the contact block’s wear-resistance and lowering the transient one. |

|
Main circuit status indicator provides exact information on the contacts status independently from lever position. |
Wide range of operating temperatures from –25 to +40° С contributes to applying this switch in different climatic zones. |

|
“TEST” button for checking the device’s operation and accuracy of connection. |
Notches on terminal clamps allow lowering thermal losses and boosting the mechanical stability of connection. |
