ABB DDA204 A 25A 30mA differential block – 4 poles

Product Code : DDA204 A-25
EAN : 8012542793908

The ABB DDA204 A differential block is a modular device designed to be installed in combination with ABB S200 series modular circuit breakers, ensuring differential protection against indirect contacts and earth leakage.

Main technical features:

• Differential type : AC (sensitive to alternating sinusoidal faults)

• Rated current (In) : 25 A

• Differential sensitivity (IΔn) : 30 mA (high sensitivity for personal protection)

• Number of poles : 4P (four poles)

• Rated operating voltage : 230/400 V AC

• Frequency : 50/60 Hz

• Mounting : 35mm DIN rail

• Connection type : with compatible ABB modular switches (e.g. S204 series)

• Class : A EN/IEC 61009-1 standard

• Compact size : 4 DIN modules

• Application : Residential, commercial and small industrial plants

Main function :
The DDA204 A differential block provides effective protection against earth leakage and protects people against indirect contact. It must be combined with a modular circuit breaker, providing a complete protection system.
