This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V. That spread covers most industrial distribution panels — the 415/440 V figures are the ones that matter for European and Asian 400 V class systems.
Thermal derating and power budget
Rated 160 A from 40 °C through 50 °C ambient; above that it derates linearly to 136 A at 70 °C.
Communication and trip unit
The ETU850 trip unit supports communication functions and other measurement functions. The base switch is 3VA2116-5KP32-0AA0; the -0AG0 suffix adds the communication-ready trip unit. Front IP40 protection.
