M54123B Overview
The UTC M54123B is a semiconductor integrated circuit with amplifier for a high-speed earth leakage circuit breaker. For the amplifying parts of earth leakage circuit breaker, the UTC M54123B consists of differential amplifier, latch circuit and voltage regulator. In normal operating, the UTC M54123B should be connected to the secondary side of the ZCT (zero current transformers).
