Technical Data Parameter Specification Product Series NZM3 (Molded Case Circuit Breaker) Product Type Electronic Trip Molded Case Circuit Breaker Rated Operational Voltage (Ue) 380 - 440 V AC Rated Insulation Voltage (Ui) 690 V / 1000 V (Please confirm with datasheet) Rated Current (In) Determined by the X-Series Rating Plug. The specific current rating (e.g., 125A, 250A, 400A) is set by installing the appropriate plug. Poles 3 Poles Mounting Style Fixed Mounting Trip Unit Type Electronic Trip Unit Protection Functions LSIG • L - Long-time Delay (Overload) • S - Short-time Delay (Short-circuit) • I - Instantaneous (Short-circuit) • G - Ground-fault Rated Ultimate Breaking Capacity (Icu) High breaking capacity. The exact value depends on the specific frame size of the NZM3 breaker and the voltage. (Example: For an NZM3 frame size N, it could be 50kA at 415V AC. Must be verified with the technical datasheet.) Communication Capability Typically ready for communication modules (e.g., for Modbus, Profibus DP). Requires a separate communication adapter. Standards IEC 60947-1, IEC 60947-2 Electrical Durability 5,000 cycles (at rated current) Mechanical Durability 10,000 cycles
