Reliable Earth Leakage Protection for Low-Frequency AC Systems
Residual current circuit breakers monitor the balance of current flowing through live and neutral conductors. If leakage current to earth creates an imbalance above the trip threshold, the RCCB disconnects the circuit quickly, helping reduce the risk of electric shock, insulation damage and electrical fire.
The ABB F202 A-63/0.03 16.7Hz is designed for installations requiring residual current protection at low AC frequency. Its 16.7 Hz compatibility makes it suitable for specialist electrical systems where standard 50/60 Hz residual current devices may not be appropriate.
Typical Applications
- Railway electrical installations.
- Low-frequency AC distribution systems.
- Specialist infrastructure power circuits.
- Control panels and switchgear assemblies.
- Electrical protection circuits requiring 16.7 Hz compatibility.
- Installations requiring 63 A Type A residual current protection.
