ABB ICST08A9 Residual Current Circuit Breaker

ABB ICST08A9

The ABB ICST08A9 is a 8A, 1P (Single Pole) Time-Delay (Type A) Residual Current Circuit Breaker (RCCB) designed for protection against earth leakage currents in electrical circuits. Below are its key technical specifications:

General Specifications:

Model: ICST08A9
Type: RCCB (Residual Current Circuit Breaker, without overcurrent protection)
Poles: 1P (Single Pole)
Rated Current (In): 8A
Rated Voltage (Un): 230V AC
Rated Residual Operating Current (IΔn): 30mA (standard for personal protection)
Residual Current Type: Type A (protects against both AC and pulsating DC residual currents)
Time-Delay Characteristic: Selective (Type S) – Delayed tripping to avoid nuisance trips in cascaded setups
Breaking Capacity (Icn): Typically 6kA (verify with datasheet)
Tripping Time: Delayed (selective, usually >130ms for Type S)

Protection Features:

Earth Leakage Protection: Yes (30mA sensitivity)
Overcurrent/Short-Circuit Protection: No (requires an external MCB for overcurrent protection)
