The A9Z61240 residual current circuit breaker from Schneider Electric is a highly advanced device designed to protect electrical installations from fault currents. This all-current sensitive circuit breaker is 2-pole and offers a rated current of 40 A as well as a rated fault current of 30 mA. It operates with a supply voltage of 230 V AC and a frequency of 50 Hz. The integrated SI technology provides improved resistance to electrical disturbances, making it particularly suitable for applications with frequency converters and inverters. The breaker is equipped with a mechanical fault indication (VisiTrip) that provides a clear display in the event of a trip due to fault current. Additionally, the safe contact indication (VisiSafe) allows for easy verification of voltage absence on the outgoing side. Installation is done on a DIN rail, and the breaker is designed for easy removal when phase rails are installed. The A9Z61240 meets relevant standards and offers a reliable solution for the protection of electrical systems.
