A9D31840 SCHNEIDER ELECTRIC

The A9D31840 from Schneider Electric is a highly reliable and efficient earth leakage circuit breaker (ELCB) designed to protect electrical circuits and prevent electrical shocks. This particular model is part of the iC60H series, known for its robust performance and safety features. It features a 1P+N (one pole plus neutral) configuration, making it suitable for single-phase electrical systems. The circuit breaker has a B curve tripping characteristic, which means it's designed to trip quickly in response to moderate overloads, providing a balance between sensitivity and preventing nuisance tripping. With a current rating of 40A, it can handle a significant amount of electrical load. The ELCB is highly sensitive to earth leakage currents, tripping at 30mA to quickly cut off the power supply in the event of a ground fault, minimizing the risk of electric shock. It is designed to operate at a voltage of 240V, which is standard for many residential and commercial applications. The A9D31840 provides reliable protection against both overloads and earth leakage faults, enhancing the safety of electrical installations. This device is essential for ensuring compliance with safety regulations and protecting people and equipment from electrical hazards. Its compact design and easy installation make it a practical choice for a wide range of applications.
