Schneider Electric Residual Current Device Acti9 iTG40 Series 40A 4-Pole 300mA Type A-SI

Schneider Electric A9Y16440 Residual Current Device from the Acti9 iTG40 Series is a precision-engineered electrical safety component rated at 40A and designed for protection against earth leakage currents. This 4-pole device offers selective earth leakage protection with a trip sensitivity of 300mA, making it suitable for complex electrical installations requiring reliable fault detection and interruption.

The device employs voltage-independent residual current tripping technology to ensure consistent performance across varying electrical conditions. It features a Type A-SI tripping characteristic for enhanced sensitivity to AC and pulsating DC residual currents.

Mounting is facilitated via a DIN Rail, enabling straightforward installation and maintenance. The compact form factor measures 91mm in height, 126mm in width, and 74mm in depth, allowing for optimized panel space usage.

The instant break time, combined with a robust breaking capacity of 40A, assures prompt disconnection during fault occurrences to improve safety of equipment and personnel. A lever actuator provides a manual reset after tripping, contributing to user-friendly operation.

The product adheres to stringent EN/IEC 61009-2-1 standards, offering assurance on quality and functional compliance within electrical distribution systems. Tunnel-type terminals accommodate secure electrical connections, minimizing wiring errors and enhancing system integrity.

It is housed in a white enclosure with an IP20 and IP40 degree of protection rating, suitable for installation in environments with pollution degree 3. This product is manufactured in Spain, reflecting high European industrial standards.

Typical applications include industrial and commercial electrical distribution boards requiring residual current protection for enhanced personnel safety and equipment protection. It is widely used in industrial automation systems, commercial buildings, and manufacturing units.
