The IP40 front protection means it's fine for indoor panel mounting where no hose-down is expected.
At 415 V the 121 kA interrupting rating puts this MCCB in the high-fault tier — suitable for main or tie breakers in industrial distribution where fault currents can hit 100 kA. The curve drops to 75.6 kA at 500 V and 4.5 kA at 690 V, so verify the available fault current at your system voltage.
The 160 A frame size uses lug terminals rated for the full continuous current; torque specs per the installation sheet.
