Residual current operated circuit breakers with over current protection DABL-63 are intended for electric shock hazard protection in case of electric installation insulation failures, for preventing fires caused by earth current leakages, overload and short circuit protection. They are recommended for protecting group lines supplying outdoor installation receptacles, appliances and garage and basement lighting.
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.
Boosted screw head dimension with cross-functional crest (+,–) helps to facilitate mounting and prevents the screws from falling out during the installation.
The DABL-63 is designed to provide protection against electric shock hazards caused by insulation failures, prevent fires resulting from earth leakage currents, and protect electrical circuits from overloads and short circuits.
It is highly recommended for protecting group lines that supply outdoor installation receptacles, domestic appliances, and lighting systems in garages and basements.
The integrated circuit ensures four distinct types of protection: protection from residual current (leakage current), protection against short circuits, protection from overloads, and protection against surge overvoltage.
The device is capable of operating efficiently across a wide temperature range, extending from -25°C to +40°C, making it suitable for diverse climatic regions.
The "TEST" button allows users to manually check the operation of the device and verify the accuracy and safety of the electrical connections.
Notches on the terminal clamps lower thermal losses and boost mechanical connection stability, while the silver-bearing composite welding deposition increases the wear-resistance of the contact block and lowers transient resistance.
