The 2.0 A provides long-time (L) overload protection and instantaneous (I) short-circuit protection — no short-time delay, so it's a straight distribution breaker, not a selective main for a downstream panelboard. The 85 kA Icu at 240 V AC and 70 kA at 415 V AC (per IEC 60947-2) tell you the interrupting capacity at the fault level the installation demands; for a 1600 A frame, that's enough for most industrial service-entrance or large sub-feed positions without cascading upstream. Fixed-mount, front-connect (both upside and downside), 280 mm wide × 327 mm tall × 147 mm deep. Backplate-mounted, not DIN-rail — plan for a dedicated enclosure cutout or a panel with the 70 mm connection pitch. The LCD display and ammeter measurement are on the front face; the four red LEDs for fault indication and one yellow for overload give local status without needing to open the door. ## Durability and thermal management Mechanical endurance is 10,000 cycles; electrical endurance at full rated current (1600 A, 690 V) is 1,000 cycles, rising to 5,000 cycles at 440 V and half-rated current. That's typical for a high-frame MCCB — the breaker is designed for infrequent switching (distribution, not motor-starting duty). The 74 W power loss at rated load means the enclosure must dissipate that heat; factor it into the thermal budget, especially if the breaker is in a sealed or multi-device panel. The 20-minute thermal memory in the MicroLogic 2.0 A trip unit tracks the heating of the conductors after a trip, so a reclose attempt too soon will hold the breaker off until the modeled temperature drops — prevents re-energizing a still-hot fault.","metaTitle":"C160H42AFM ComPacT NS, 1600 A, 4P, MicroLogic 2.0 A, 85 kA","metaDescription":"C160H42AFM ComPacT NS new generation, 1600 A at 50 °C, 4P, MicroLogic 2.0 A trip unit, 85 kA Icu at 240 V.
