Key Features A9R14491

• High Load Capacity: 100A rating allows use in systems with large electrical loads or high current requirements.

• 300mA Sensitivity: Designed for fire protection by detecting medium-level residual currents that may not be harmful to humans but can cause overheating.

• Four-Pole Design: Ensures full disconnection of all lines and neutral for maximum system protection.

• Type AC Sensitivity: Suitable for most general-purpose electrical installations where only AC leakage is expected.

• Instant Response: Trips quickly upon detection of residual current above the set threshold, preventing system damage.

• Integrated Test Button: Simple manual testing for regular inspection and maintenance.

• Compact Modular Housing: Saves space in distribution boards and allows integration into standard panels.

Typical Applications

Commercial Buildings
Used in power distribution systems of offices, retail spaces, and institutions to prevent fire risks and protect equipment from earth faults.

Industrial Facilities
Protects motors, control circuits, lighting systems, and industrial panels from residual current faults that could lead to overheating or equipment damage.

Large Residential Projects
Suitable for apartment buildings, villas, and residences using 3-phase systems with high power demands.

Fire Prevention Installations
Ideal for locations where reducing the risk of electrical fires is more important than personal shock protection, such as archives, storage areas, and mechanical rooms.

Main Distribution Boards
Acts as a primary protection device in the main incomer section of switchboards or panels, ensuring that any serious ground fault is detected before it spreads.
