The ABB RCCB F202 AC-40/0.03 is a part of the F200 series of Residual Current Circuit Breakers (RCCBs) designed to provide comprehensive protection for both individuals and electrical installations against ground fault currents. These RCCBs come in a variety of configurations to suit various applications and are available in standard instantaneous and selective AC and A types. The F202 AC-40/0.03 is specifically designed as an AC type RCCB and offers the following specifications:
Type of Residual Current: AC type
Rated Voltage (Ur): 230 V
Rated Operational Voltage: 230 V
Rated Insulation Voltage (Ui): 500 V
Rated Impulse Withstand Voltage (Uimp): 4 kV
Rated Current (In): 40 A
Rated Residual Current: 30 mA
Rated Conditional Short-Circuit Current (Inc): 10 kA
Rated Service Short-Circuit Breaking Capacity (Ics): 1 kA
Maximum Surge Current: 0.25 kA
This RCCB is primarily used for detecting and interrupting abnormal currents caused by faults to the ground. It can handle a rated current of 40 A and provides protection against residual currents of 30 mA, which can be crucial for safeguarding against electric shocks and fires. The RCCB is rated for a short-circuit current of 10 kA and has a service short-circuit breaking capacity of 1 kA, ensuring it can safely interrupt faults in the electrical system.
The maximum surge current handling capacity of 0.25 kA makes it suitable for managing transient electrical surges and spikes, which can occur due to lightning strikes or other external factors. The high insulation voltage rating of 500 V and impulse withstand voltage of 4 kV further enhance the safety and reliability of this RCCB, making it a valuable component in electrical distribution systems.
