Schneider Electric NE12CT2 Neutral Current Transformer

Schneider Electric’s NE12CT2 Neutral Current Transformer is a dedicated CT kit designed to accompany Square D NE/NX molded‑case circuit breakers with Series 3 Micrologic protection. It provides neutral current sensing to the Micrologic trip unit, enabling protection and metering of currents returning through the system neutral. The NE12CT2 is specified for a 1,200 A primary current, identifying it as Schneider Electric’s 1200 A neutral current transformer for NE/NX installations. Used inside the breaker enclosure, this CT integrates with the protection scheme to feed the neutral current measurement the Micrologic logic requires for accurate fault detection and monitoring.
