Specifications Parameter Specification Product Series Compact NSX Product Line NSX400F (Fixed version) Number of Poles 3 Poles (3P) Rated Operational Current (In) 320 Amperes (This is the set/rated current of the trip unit within the 400A frame) Frame Size 400A Frame (Maximum current rating for this physical size) Trip Unit Type Micrologic 2.3 (Electronic Trip Unit) Trip Unit Code 2.3M – "M" indicates the current rating (Ir) setting range. This typically corresponds to a unit adjustable within a range that includes 320A (e.g., a 250-400A range). Protection Functions LSI Protection: • L (Long-time): Adjustable Ir & tr for overloads • S (Short-time): Adjustable Isd & tsd for selective short-circuits • I (Instantaneous): Fixed Ii for ultimate short-circuit protection Breaking Capacity (Icu) 50 kA / 70 kA / 100 kA @ 400V AC (Specific level depends on the catalog suffix, e.g., N, H, L) Rated Operational Voltage (Ue) 690 V AC Rated Insulation Voltage (Ui) 1000 V AC Frequency 50/60 Hz Selectivity Excellent. The adjustable short-time delay (tsd) enables selectivity with downstream devices, limiting outage to the faulty circuit only. Connection Front or rear connection Mounting Fixed mounting (panel or DIN rail adapter) Width Approximately 105 mm (for 3-pole fixed version) Standards IEC/EN 60947-2, UL 489, CCC, CE Communication Optional. Micrologic 2.3 units can be equipped with communication modules (e.g., for Modbus, Profibus) for remote monitoring and control. Display Typically includes an LED or LCD display for status, alarms, and real-time current measurement.
