Automatic phase switch 16A 230V/3x400V+N APM-10 (EXT10000202)

The general automatic phase switch is used to supply a single-phase industrial and household installation of 230 V/50 Hz from a three-phase 4-wire network 3x400+N to ensure interference-free power supply. It protects against unacceptable voltage fluctuations in the network.

Depending on the presence and quality of the voltage in the phases, the APM-10 automatically selects the phase with the best parameters and switches a single-phase load to that phase from any other.

• When the power does not exceed 3.5 kW (16 A), the load is supplied directly from the APM-10.
• When the power exceeds 3.5 kW (16 A), the phase switch controls the coils of the external contacts.

The external relay is not included in the delivery scope. The minimum and maximum voltage limits are defined by the user.
