A9D77420 SCHNEIDER ELECTRIC

The Acti9 iC60 RCBO A9D77420 from Schneider Electric is a 4-pole residual current circuit breaker with overcurrent protection, designed to safeguard electrical circuits from both overload/short-circuit and earth leakage faults. It has a current rating of 20A and a C curve tripping characteristic, making it suitable for applications with moderate inrush currents. The device offers a breaking capacity of 6000A according to IEC/EN 61009-1 and 6kA according to IEC/EN 60947-2, ensuring reliable protection in various electrical installations. Its 30mA sensitivity provides effective protection against indirect contact hazards. The SI (Super Immunized) type offers enhanced immunity against nuisance tripping due to transient overvoltages or high-frequency currents. This RCBO combines the functionalities of a circuit breaker and a residual current device in a single unit, saving space and installation time. It is part of the Acti9 range, known for its quality, reliability, and safety features. It is suitable for residential, commercial, and industrial applications. The A9D77420 RCBO contributes to ensuring the safety of people and equipment by quickly disconnecting the faulty circuit in case of an earth leakage or overcurrent event.
