. Key Features

• High Current Rating (80A): Suitable for main circuit protection in high-demand installations.

• 300mA Sensitivity: Provides protection against fire hazards caused by high earth leakage currents.

• Type AC Detection: Suitable for typical domestic and commercial applications where only AC leakage is expected.

• Dual-Pole Switching: Disconnects both phase and neutral for improved safety and isolation.

• Compact Design: Takes only 2 DIN modules (36 mm), ideal for use in modern switchboards.

• Mechanical Indicator: Clearly displays ON/OFF/trip status for fast fault identification.

• Integrated Test Button: For regular function testing to ensure device integrity.

• No Load Protection: Should be paired with a circuit breaker (MCB) for overcurrent protection.

• Tool-Free Installation: Designed for fast and easy DIN rail mounting.

. Applications

The A9R14280 RCCB is primarily used for equipment and fire protection, rather than personal shock protection, due to its 300mA residual current rating. Suitable applications include:

• Main Incoming Protection: In residential and commercial distribution panels.

• Fire Prevention: Detects high leakage currents that may lead to overheating or fire, especially in aging electrical systems.

• Large Residential Installations: Protection for entire houses or villas with high current requirements.

• Commercial Buildings: Offices, retail spaces, or small industrial workshops requiring robust leakage protection.

• Sub-Distribution Boards: For partial or segmented protection of large installations.
