A9D27220 SCHNEIDER ELECTRIC

The Acti9 iC60 RCBO A9D27220 from Schneider Electric is a 2-pole Residual Current Breaker with Overcurrent protection (RCBO), designed to safeguard electrical circuits from both overload/short-circuit and earth leakage faults. It has a rated current of 20A and a C curve tripping characteristic, making it suitable for a wide range of applications with moderate inrush currents. The device offers a high breaking capacity of 10000A according to IEC 60898-1 and 15kA according to IEC 61009-1, ensuring reliable protection even in demanding electrical environments. Its sensitivity to residual current is 30mA, providing effective protection against electric shock. The SI type (Super Immunized) indicates enhanced immunity to nuisance tripping caused by transient overvoltages or high-frequency currents. This RCBO combines the functions of a Miniature Circuit Breaker (MCB) and a Residual Current Device (RCD) in a single compact unit, saving space in electrical panels. It is part of the Acti9 range, known for its quality, reliability, and safety features. The A9D27220 RCBO is ideal for use in residential, commercial, and industrial applications where both overcurrent and earth leakage protection are required. It contributes to ensuring the safety of people and equipment by quickly disconnecting the circuit in the event of a fault.
