Key Features:

• Four-Pole Earth Leakage Protection
  Provides full-phase and neutral protection by disconnecting all poles in the event of an earth fault.

• 30 mA Sensitivity
  Offers enhanced protection for human life by detecting small leakage currents that may cause electric shock.

• Class AC Detection
  Suitable for general AC applications—detects sinusoidal residual currents only.

• Modular Design
  Attaches directly to Schneider Acti9 C120 4P MCBs to form a complete protection device.

• User-Friendly Installation
  Snap-on mechanism allows quick and easy integration into existing distribution systems.

• Compact and Efficient
  Saves panel space while adding crucial safety functionality.

• Dual Protection Function
  When combined with a C120 MCB, provides both overcurrent and earth leakage protection, similar to an RCBO.

Applications:

• Residential and Commercial Buildings
  Protects lighting, socket outlets, and other circuits where personal protection is required.

• Industrial Distribution Boards
  Ensures safe disconnection in three-phase systems with neutral.

• Public and Healthcare Facilities
  Essential for environments where high safety standards are required, including schools, hospitals, and offices.

• General-Purpose Electrical Installations
  Suitable for most AC systems needing reliable residual current protection.

• New Installations and Retrofits
  Easily integrates into new setups or upgrades of existing protection systems.
