Its TM110M thermal-magnetic overcurrent release gives it a fixed trip curve tuned for motor-starting inrush without nuisance trips, while the magnetic element clears short circuits fast. The 3-pole form factor fits standard MCCB panel mounting.
At 415 V the rating drops to 121 kA, at 440 V to 75.6 kA, and at 500 V and 690 V it holds at 7.5 kA. For an engineer sizing panel SCCR, the lowest voltage you're working at governs coordination: if your supply transformer can deliver 100 kA at 415 V, this breaker has headroom. The steep drop above 440 V reflects the physical limits of air as an arc-quenching medium at higher voltages.
Depth of 70 mm means it will clear typical backpanel wiring gutters without forcing a deeper enclosure.
