A9DE3720 SCHNEIDER ELECTRIC

The A9DE3720 from Schneider Electric's Acti9 iCV40 series is a 3P+N residual current breaker with overcurrent protection (RCBO), designed to safeguard electrical circuits from both overcurrents and residual current faults. This RCBO combines the functionality of a miniature circuit breaker (MCB) and a residual current device (RCD) in a single unit, offering space-saving and efficient protection. It has a current rating of 20A and a C curve tripping characteristic, making it suitable for a wide range of applications with moderate inrush currents. The device is designed to trip at 30mA residual current, providing sensitive protection against electric shock. It has a breaking capacity of 6000A, ensuring reliable performance under fault conditions. The AC type designation indicates its suitability for detecting AC residual currents. The Acti9 series is known for its modularity and ease of installation, making it a preferred choice for electrical professionals. This RCBO is ideal for use in residential, commercial, and industrial settings where both overcurrent and residual current protection are required. It helps to ensure the safety of people and equipment by quickly disconnecting the circuit in the event of a fault.
