Breaking capacity by voltage level
The interrupting rating is voltage-dependent: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. At the common 415 V distribution level, 121 kA gives substantial headroom for high-fault installations — useful when the MCCB is the first device after a transformer or in a paralleled-generator setup.
Integrated undervoltage release
No auxiliary switch is fitted, so if you need a separate status contact for the PLC, plan for an external auxiliary block.
The 110 mm depth is the projection from the mounting surface, which matters when the panel door clearance is tight.
