Key Features
-
63A Rated Current: Suitable for low- to medium-power circuits requiring protection against earth leakage currents.
-
300mA Sensitivity: Designed for fire prevention, this RCCB detects residual currents that could cause overheating or other risks associated with prolonged leakage currents, especially in systems where human safety is less of a concern than fire protection.
-
Type AC Detection: Specifically designed to detect sinusoidal AC leakage currents that are typically found in general residential and commercial systems.
-
Instantaneous Tripping: Instantly trips when the leakage current exceeds the rated threshold, ensuring rapid disconnection to avoid potential fire hazards.
-
Test Button: Allows for regular manual testing of the RCCB to ensure its functionality.
-
Compact and Modular Design: Space-saving and easy to install on DIN rails, making it an ideal choice for distribution panels.
-
Compliance with IEC Standards: Meets the IEC 61008-1 standard for electrical safety and reliability.
Applications
The A9R44263 RCCB is ideal for use in applications where the primary concern is fire protection due to residual current leakage. Its 300mA sensitivity makes it suitable for:
Residential Installations
-
Protection for household appliances and lighting systems, where fire prevention is the key concern due to extended leakage currents over time.
Commercial Installations
-
Suitable for retail spaces, offices, and small commercial buildings, providing safety for electrical systems in areas where personnel are less likely to come into direct contact with live conductors.
Industrial Environments
-
Ideal for protecting circuits in workshops, warehouses, and other industrial facilities that use three-phase or two-phase systems.
Electrical Distribution Panels
-
Provides residual current protection in main electrical panels where extended leakage currents may be a concern, especially for older systems or systems with deteriorating insulation.
