    Residual Current Circuit Breaker with Liquid Crystal Display (RCCB with LCD Type): Functions and Benefits

    Trip Status Display: When a fault occurs, the RCCB with LCD display provides a clear indication of the trip status, including the cause of the trip and the time of occurrence. This information is valuable for diagnosing the root cause of electrical issues and implementing corrective measures. Historical Data Logging: RCCBs with LCD displays are capable of logging historical data related to electrical events and faults. This data can be used for analysis, trend monitoring, and compliance with regulatory requirements.
