Block diff 4p max 25a 0.3a ac 2

The ABB DDA204 AC-25/0.3 differential block is a device designed to be combined with the S200 and S300P series miniature circuit breakers. This combination offers complete protection against overloads, short circuits and earth leakage currents.

Main features:

• Rated current (In): 25 A

• Differential sensitivity (IΔn): 300 mA

• Number of poles: 4

• Differential current type: AC (sensitive to sinusoidal fault currents)

• Rated operating voltage (Ue): 230/400 V

• Breaking capacity: 6 kA

Main functions:

• Protection from indirect contact: Intervenes in the event of leakage currents towards earth, preventing the risk of electrocution.

• Overload and Short Circuit Protection: When combined with an appropriate circuit breaker, it provides complete circuit protection.

• Easy to assemble: Designed for quick and secure mating with S200 and S300P series switches.
