It's rated 100 A at 40 °C, 4 poles, and carries an 85 kA Icu breaking capacity at 500 V AC 50/60 Hz per IEC 60947-2. The 6.2 E trip unit provides L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and G (ground fault) protection — the 'E' designation means it includes energy metering and power quality measurement, not just protection. This is a distribution-grade device (Category A) for backplate mounting, with front connections both top and bottom.
The HB1 breaking capacity code means 75 kA Icu at 690 V AC, but the full curve is 85 kA at 500 V, 80 kA at 525 V, and 75 kA at 660/690 V. For a 480 V or 400 V distribution panel, that 85 kA Icu at 500 V gives substantial headroom above typical utility fault levels. The 4-pole frame with neutral on the left handles 3-phase plus neutral distribution without a separate neutral breaker. The 20,000-cycle mechanical durability and 20,000-cycle electrical durability at 440 V In/2 (10,000 at full In) are typical for a panelboard main or feeder breaker — not a daily-switched disconnect, but fine for infrequent manual operation.
Trip unit and metering
The MicroLogic 6.2 E is an electronic trip unit with an LCD display and local signalling: a flashing green LED for ready, red LED at 105% Ir for overload, orange at 90% Ir. It communicates instantaneous and demand values, protection and alarm settings, power quality, energy metering, maintenance indicators, and time-stamped event tables.
Connection pitch is 35 mm. Pollution degree 3 per IEC 60664-1, overvoltage category III, operating altitude 0–2000 m without derating, 2000–5000 m with derating. Relative humidity 0–95%. IK07 impact protection per IEC 62262. The toggle control and LCD display are front-accessible.
