The A9Z66480 IID 4P 80A 500mA 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 80A and a rated residual current of 500mA, this device provides reliable protection against fault currents that can be caused by electrical disturbances. The circuit breaker is all-current sensitive and is suitable for both single-phase and three-phase supply networks, particularly in applications with frequency converters and inverters. The integrated SI technology ensures improved disturbance resistance, enhancing the safety and reliability of the electrical installation. The A9Z66480 is designed for mounting on DIN rails and allows for easy removal of the individual device, facilitating maintenance. With additional modular auxiliary components, the circuit breaker can be tailored to specific requirements.
