The A9Z64225 IID 2P 25A 300MA Type B-SI residual current circuit breaker from Schneider Electric is a highly advanced device designed specifically for use in electrical installations. With a rated current of 25A and a rated residual current of 300mA, this device provides reliable protection against fault currents that can be caused by electrical disturbances. The Type B-SI is equipped with integrated SI technology, ensuring improved resistance to electrical disturbances. The circuit breaker is suitable for operation in single-phase or three-phase supply networks and is particularly effective against smooth DC fault currents, which are commonly found in applications with frequency converters or inverters. Installation is straightforward on a DIN rail, and the front-facing fault indication (VisiTrip) allows for quick checking of the device status. Additionally, the breaker features a safe contact indication (VisiSafe) that signals the absence of voltage on the outgoing side.

• Mechanical fault indication (VisiTrip) to show tripping due to fault current
• Safe contact indication (VisiSafe) for absence of voltage on the outgoing side
• Test button for regular functional testing
• Double connection terminals for both-sided connection of cables or busbars
• Easy removal of the individual device with the busbar installed, thanks to the front-accessible fastening element.
