Technical characteristics of the ABB DDA204 Differential Block
The Abb DDA204 63A 4 pole 300mA 4 module B273292 differential block brings with it a series of technical specifications that make it an excellent choice for various types of installations. Let's take a closer look at its main features:
Differential Lock Specifications
- Nominal voltage: 230...400V
- Rated current: 63A
- Number of poles: 4
- Rated residual current: 300mA
- Size in modules: 4
These specifications make the DDA204 highly versatile and suitable for a wide range of applications, while ensuring safety and reliability.
Compatibility and Applications
The ABB DDA204 Differential Block not only excels in its technical specifications but also in its flexibility of use. It is designed to be efficiently coupled to the S 200 L, S 200, S 200 M, S 200 P series circuit breakers to offer complete circuit breaker protection.
Furthermore, there is the possibility of coupling the DDA204 with magnetic-only switches of the M 200 series . In this scenario, to ensure optimal protection against overload currents, it is necessary to implement additional thermal protection. This further expands the potential applications of the RCD lock, making it a flexible solution for multiple electrical protection needs.
