Differential Block for Switch S200 A 40A 30mA 2P ABB B427955
The DDA 200 Differential Block features high compatibility with various series of circuit breakers, making it a key element for creating circuit breaker protection systems.
Features of the DDA 200
Highly appreciated for its flexibility in coupling with the S 200 L, S 200, S 200 M, S 200 P series switches, it allows the implementation of effective protection systems against differential currents.
- It performs magnetothermal differential protection function.
- Can be coupled with switches of the S 200 L, S 200, S 200 M, S 200 P series.
Additional Protection with DDA 200
The DDA 200 can also be used in combination with the magnetic-only switches of the M 200 series. In this case, to protect against overload currents, we recommend adding a thermal protector.
- Compatible with M 200 magnetic only switches.
- Requires additional thermal overload protection.
