It is a 4-pole, manually operated unit rated 800 A at 50 °C, fitted with a MicroLogic 6.0 electronic trip unit that provides L (long-time overload), S (short-time short-circuit), I (instantaneous short-circuit), and G (ground fault) protection. Its breaking capacity reaches 85 kA Icu at 220/240 V AC and 70 kA Icu at 380/415 V AC, both per IEC 60947-2.
The 800 A trip unit rating at 50 °C sets the continuous current capacity. The electronic trip unit includes thermal memory (20 min) that retains heat history after a trip. Breaking capacity varies by voltage: 85 kA at 240 V, 70 kA at 415 V, 65 kA at 440 V, 50 kA at 525 V, and 42 kA at 690 V. For a 415 V system, the 70 kA Icu provides ample headroom for most industrial installations; coordination studies should verify selectivity with downstream devices. The breaker is rated IP40 (finger protection) and IK07 (impact resistance to 2 J), suitable for indoor panel environments.
