Description
ABB Residual Current Breaker with Overcurrent Protection (RCBO) DS201L 4500 APR y type, C characteristic High Immunity 4.5kA, C-Curve
The ABB DS201L 4500 AP-R Type A RCBO (Residual Current Circuit Breaker with Overcurrent protection) is engineered for superior circuit protection in single-phase end-user circuits. This compact 1P+N device safeguards against:
- Overload and Short-Circuit Currents.
- Sinusoidal Alternating and Direct Pulsating Earth Fault Currents (Type A).
- Indirect and Additional Direct Contacts (typically at IΔn=30mA).
AP-R (High Immunity) Technology:
The key differentiator of the AP-R version is its resistance to nuisance tripping. This feature ensures maximum continuity of service by avoiding unnecessary interruptions in systems where equipment like LED lighting, computer power supplies, and variable speed drives generate transient leakages and noise.
The C characteristic curve makes it perfectly suited for general domestic and light industrial loads.
