典型应用 (Typical Applications):
The Eaton NZMS2-A200 is a 200-ampere, 3-pole, molded case circuit breaker (MCCB) from the industrial-grade Eaton NZM series.
The "NZMS2" identifies the specific frame size within the NZM family, which is larger than the NZMS1 frame and designed for higher current ratings. The "A" typically denotes a specific interrupting capacity rating for this frame. The "200" specifies the fixed rated current of this unit, which is 200 Amperes.
