It is a manually operated, fixed-mount 3-pole breaker rated 1600 A at 50 °C, with an electronic MicroLogic 5.0 E trip unit that provides L (long-time overload), S (short-time short-circuit), and I (instantaneous short-circuit) protection plus integrated energy metering.
Rated 85 kA Icu at 220/240 V AC, 70 kA Icu at 380/415 V AC, and 42 kA Icu at 660/690 V AC per IEC 60947-2. That 70 kA at 415 V gives solid selectivity headroom in a 400 V distribution panel — downstream breakers can coordinate without nuisance tripping on a bolted fault.
Trip unit and metering
It includes an energy meter — so you get load profiling and power data without a separate meter module. The thermal memory holds for 20 minutes after a trip, which means the breaker remembers the heat profile if you reclose quickly; useful for motor or transformer feeders that see repeated starts.
Fixed mount on a backplate, 210 mm wide × 327 mm high × 147 mm deep. Connection pitch is 70 mm, with front-facing upside and downside connections — that keeps cable entry and exit on the same plane, simplifying busbar or cable routing in a switchboard. IP40 front face, IK07 impact rating.
