The Schneider Electric Acti9 Vigi C120 (A9N18576) is a modular earth leakage add-on block designed to enhance electrical safety. This device is engineered for 3-pole (3P) protected circuits, operating at a rated current of 125A, and is commonly integrated into residential and small commercial electrical distribution systems to prevent hazards associated with earth faults.

Technical details

• Series: Acti9 Vigi C120
• Protected Poles: 3P
• Rated Current: 125A
• Earth-Leakage Sensitivity: 300mA
• Type: Earth Leakage Add-on Block
• Mounting: DIN rail compatible (standard for modular devices)
• Voltage Rating: Verify against manufacturer datasheet for specific voltage class (e.g., 230/400V AC).
• Breaking Capacity: Verify against manufacturer datasheet.

Applications & compatibility

This earth leakage add-on block is suitable for use in main distribution boards and sub-distribution boards within residential buildings, small commercial facilities, and light industrial settings. It provides essential protection against indirect contact in applications where standard overcurrent protection is insufficient to mitigate earth leakage risks.
