## Summary description

The Doktorvolt DV-4247 is a 4-pole residual current circuit breaker (RCCB) designed for electrical safety. It features a 40A rated current, 30mA sensitivity, and 10kA short-circuit capacity. This Type A device provides reliable protection against residual currents in AC and pulsating DC systems, ensuring safety in residential and industrial electrical installations.

## Long description

The Doktorvolt DV-4247 is a high-performance 4-pole residual current circuit breaker (RCCB) engineered to provide essential electrical safety in both residential and industrial environments. This device is designed to detect and interrupt electrical circuits when a residual current is detected, effectively preventing electric shocks and mitigating the risk of fire caused by insulation faults. With a robust construction and reliable switching mechanism, it serves as a critical component in modern electrical distribution boards.
Advantages
The primary advantage of this RCCB is its Type A classification, which allows it to detect not only standard alternating residual currents but also pulsating direct residual currents. This makes it a versatile solution for protecting modern electronic equipment that may introduce DC components into the electrical system. The device features a high short-circuit capacity of 10kA, ensuring durability and safety even under demanding electrical conditions. Its 4-pole configuration allows for comprehensive protection in three-phase systems, providing a balanced and secure electrical installation.
Suitable for
Residential electrical distribution boards
Industrial machinery and equipment protection
Commercial building electrical systems
Installations with electronic devices that produce pulsating DC currents
When it may not be suitable
This device is not intended for use in DC-only electrical systems or high-frequency circuits that fall outside the operational parameters of a Type A RCCB. It should not be used as a substitute for a miniature circuit breaker (MCB) as it does not provide protection against overcurrent or short-circuit conditions.
Key specifications
Number of poles: 4
Rated current: 40A
Rated residual operating current: 30mA
Short-circuit capacity: 10kA
Type: A
How to use
The Doktorvolt DV-4247 must be installed by a qualified electrician in accordance with local electrical regulations. It is designed for mounting on a standard DIN rail within an electrical distribution cabinet. Ensure that the supply cables are correctly connected to the input terminals and the load cables to the output terminals, observing the correct polarity and phase sequence. After installation, the device should be tested using the integrated test button to verify its mechanical and electrical functionality.
What to consider before purchase
Verify that the rated current of 40A is sufficient for your specific circuit load.
Ensure the 30mA sensitivity meets the safety requirements for your installation type.
Confirm that the 4-pole configuration is compatible with your existing three-phase electrical system.
Check that the space available in your distribution board is adequate for a 4-module wide device.
Usage recommendations
Regularly press the test button at least once every six months to ensure the internal mechanism remains operational and the device trips correctly in the event of a fault.
