Leakage current detection IC "RT8H044K"
Leakage detection IC with a built-in abnormal voltage detection function and a 1.5-wave, 3-pulse counting method!!
This product is an IC developed for leakage detection circuits for leakage protection, which connects a ZCT to the input terminal and detects the current generated through the ZCT when a leakage occurs. It uses a 1.5-wave 3-phase counting method, making it resistant to noise and optimal for leakage circuit breakers. It also has a built-in abnormal voltage detection function, allowing it to be used for neutral line phase loss protection. This abnormal voltage detection function can be disabled by connecting the PSAV terminal to GND. Additionally, the output format employs intermittent output, preventing damage to the trip coil in case of incorrect connections.
