Schneider Electric Acti9 iID Differential 4P 25A 300mA B-SI

The Schneider Acti9 iID A9Z64425 differential is a highly reliable and safe residual current circuit breaker (RCCB), designed to protect both people and installations against electric shocks from indirect contact and fire risk due to earth leakage.

This 4-pole model has a rated current of 25 A and a sensitivity of 300 mA, being of type AC, which makes it suitable for standard applications in residential, tertiary, and industrial electrical installations. It complies with insulation requirements according to IEC 61008-1, IEC 61008-2-1, IEC 62423, IEC 61543, and VDE 0664 standards.

The design of this device includes a mechanical trip indicator on the front (red color), allowing quick identification of the disconnection origin, thus reducing diagnosis and maintenance times. It also incorporates the VisiSafe function, a safety window with a green band visible when all poles are completely open, ensuring safety during downstream maintenance tasks.
