ComPacT NSX with MicroLogic 6.2 E — 100 A, 85 kA Icu
It carries a MicroLogic 6.2 E electronic trip unit rated 100 A at 40 °C, providing L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and G (ground fault) protection per EN/IEC 60947-2. The breaking capacity is 85 kA Icu at 500 V AC 50/60 Hz, 80 kA at 525 V, and 75 kA at 660/690 V — the HB1 code indicates 75 kA at 690 V AC. The IP40 enclosure (IK07 impact resistance) suits indoor panel installation where splash and mechanical knock are limited.
Trip unit and metering capability
It communicates power quality data, demand current and power, protection and alarm settings, time-stamped histories and event tables, maximeters/minimeters, maintenance indicators, and instantaneous/demand values. The LCD display provides local signalling: a flashing green LED for ready-to-operate, red LED at 105 % Ir for overload, and orange LED at 90 % Ir for overload. Pollution degree 3 (IEC 60664-1) and overvoltage category III are specified, confirming suitability for fixed installations in industrial environments.
Durability and environmental limits
Electrical durability varies by load: 20,000 cycles at 440 V In/2, 10,000 cycles at 440 V In, 10,000 cycles at 690 V In/2, and 5,000 cycles at 690 V In. The utilisation category is A (no intentional short-time delay for selectivity with downstream breakers on the same level). Operating altitude is 0 to 2000 m without derating, 2000 m to 5000 m with derating. Relative humidity range is 0 to 95 %.
