Hager ST Bell Transformer – ST305

A doorbell transformer ensures the proper operation of the doorbell. Because a doorbell operates on low-voltage electricity, it cannot be connected to 230V. This Hager ST bell transformer converts the power supply to the correct number of volts. The Hager ST bell transformer is short-circuit proof.
