What this MCCB does and where it fits
The frame has a 150 A minimum and 1 200 A maximum current setting range.
Interrupting ratings drop as system voltage rises: 440 kA at 240 V, 330 kA at 415 V and 440 V, 220 kA at 500 V, and 52.5 kA at 690 V.
Thermal performance — it holds 100 A all the way to 70 °C
Max power loss is 7.7 W.
Ground-fault and communication options
This variant includes ground-fault monitoring via summation current formation on the L-conductor — it detects leakage by summing phase currents, so you don't need a separate GFCI module. Communication function is present, which means it can integrate with a building management or power-monitoring system over the SENTRON communication bus. That covers unheated electrical rooms and outdoor enclosures in most climates.
