M54123L Overview
The UTC M54123L 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 M54123L consists of differential amplifier, latch circuit and voltage regulator. In normal operating, the UTC M54123L should be connected to the secondary side of the ZCT (zero current transformers).
