Description
FH Series RCCBs
The FH series from ABB includes Residual Current Circuit Breakers (RCCBs) designed to offer reliable protection against leakage currents in electrical circuits. These devices are engineered for use in residential, commercial, and industrial installations where high levels of safety and performance are required.
Key Features:
High Protection Level: The FH series provides excellent protection against leakage currents, preventing electric shocks and electrical fires caused by earth leakage. It is ideal for high-performance applications where safety is critical.
High Breaking Capacity: The FH series RCCBs can withstand short-circuit currents up to 1 kA, ensuring robust protection for the system and minimizing risks in case of faults.
Wide Sensitivity Range: Available in 30 mA, 100 mA, and 300 mA sensitivity ratings, the FH seriesmeets various application requirements from residential to more demanding commercial and industrial applications.
Modular and Compact Design: These RCCBs are designed for easy installation on DIN rails and occupy minimal space, making them suitable for installations where panel space is limited.
No Overcurrent Protection (Only RCCB): Unlike RCBOs, the FH series offers residual current protection only, providing excellent protection against leakage currents but without overcurrent protection.
Compliance with International Standards: The FH series RCCBs are designed in accordance with IEC/EN 61008, ensuring global compatibility and reliability.
Applications:
Residential Protection: Protects household circuits from leakage currents, providing safety against electric shock and preventing potential fire hazards.
Commercial Use: Ideal for protecting circuits in commercial spaces such as offices, shops, and small businesses, ensuring that leakage currents are effectively detected and isolated.
Industrial and Infrastructure Applications: Suitable for medium-voltage installations and critical systems that require reliable protection against leakage currents, helping to avoid electrical hazards in high-risk areas.
Conclusion:
The ABB FH Series RCCBs provide essential protection for a wide range of applications. Offering high sensitivity and reliable performance, they are perfect for protecting circuits against earth leakage. With a compact design and high breaking capacity, these RCCBs are ideal for residential, commercial, and industrial use, ensuring safety and compliance with international electrical standards.
