The Acti 9 iID is a type of DIN Rail Residual Current Circuit Breaker (RCCB) manufactured by Schneider Electric, specifically designed to provide protection against earth leakage faults. Here's an overview:

Acti 9 iID RCCB Overview:

1. Residual Current Protection: The Acti 9 iID RCCB is designed to detect and interrupt abnormal currents caused by earth leakage faults. These faults occur when current flows from the live conductor to earth due to insulation breakdown, equipment faults, or electrical faults.
2. DIN Rail Mounting: The iID RCCB is designed for easy installation on DIN rails, commonly used in electrical distribution panels and enclosures. This makes it suitable for a wide range of residential, commercial, and industrial applications.
3. Current Ratings: The Acti 9 iID RCCB is available in various current ratings, with models capable of handling currents up to 100 amps. This range accommodates different applications and load requirements.
4. Coordination with MCBs: The iID RCCB can be coordinated with Acti 9 and Multi 9 Miniature Circuit Breakers (MCBs) to provide additional protection against direct contact. This coordination ensures comprehensive protection for electrical circuits and equipment.
5. Safety Features: The iID RCCB is equipped with safety features such as test buttons for periodic testing of its operation and indication mechanisms to signal when it trips due to earth leakage faults.
6. Compliance: The Acti 9 iID RCCB complies with relevant international standards and regulations for electrical circuit protection devices, ensuring safety, reliability, and performance.
7. Additional Protection: In addition to providing protection against earth leakage faults, the iID RCCB offers supplementary protection against direct contact, further enhancing electrical safety.

Overall, the Acti 9 iID RCCB offers reliable and comprehensive protection against earth leakage faults, making it an essential component of electrical installations where safety and reliability are paramount.
