Differential Block for Switch S200 AC 25A 30mA 3P ABB B427925
The ABB B427925 Differential Block is designed to be coupled with a careful selection of circuit breakers. The S 200 L, S 200, S 200 M, S 200 P series constitute the complete range of circuit breakers suitable for fully exploiting the potential of the Differential Block. Its main role is to optimize the circuit breaker differential protection function.
Compatible Switch Series (Magneto-thermal and Magnetic Only)
- S 200 L
- S 200
- S 200 M
- S 200 P
This extensive compatibility makes the Differential Lock extremely versatile and suitable for different configurations.
Mating with Magnetic Only Switches
The DDA 200 Differential Block can also be coupled with the magnetic-only switches of the M 200 series. In this case, to ensure effective protection against overload currents, it is necessary to provide additional thermal protection.
