The Acti 9 Vigi for iC60 and C120 are add-on residual current devices (RCDs) designed to enhance the protection provided by Acti 9 iC60 and Acti 9 C120 miniature circuit breakers (MCBs), including RCBOs (Residual Current Circuit Breakers with Overcurrent Protection), which integrate MCB and RCD functions in a single unit. Here's an overview of these Vigi modules:

Acti 9 Vigi for iC60 and C120 Overview:

1. Modular Design: These Vigi modules are designed to be installed alongside Acti 9 iC60 and C120 MCBs, adding residual current protection to the circuit. They are typically used as add-on devices to provide additional safety against earth leakage faults.
2. Compatibility: The Vigi modules are compatible with Acti 9 iC60 and C120 MCBs, including RCBOs, which are rated for currents up to 125A. This compatibility allows for seamless integration into electrical distribution panels and enclosures.
3. Rated Current: The Vigi modules support rated currents up to 125A, providing protection for a wide range of applications with varying load requirements.
4. Earth Leakage Protection: These Vigi modules offer earth leakage protection, detecting and tripping the circuit in the event of earth fault currents. This helps prevent electric shocks and reduces the risk of fire hazards in electrical installations.
5. Sensitivity: The Vigi modules typically have a sensitivity of 30mA, meaning they can detect leakage currents as low as 30 milliamps, ensuring effective protection against earth faults.
6. Enhanced Safety: By adding residual current protection to the MCBs, the Vigi modules enhance the safety of electrical installations, providing comprehensive protection against earth leakage faults, electrical shocks, and fire hazards.
7. Ease of Installation: These Vigi modules are designed for easy installation alongside Acti 9 iC60 and C120 MCBs, simplifying the process of adding residual current protection to electrical circuits.

Overall, the Acti 9 Vigi for iC60 and C120 modules are essential components for enhancing the safety and protection provided by Acti 9 MCBs, including RCBOs, in electrical installations. They offer reliable earth leakage protection and contribute to the overall safety and reliability of the electrical distribution system.
