Rated 125 A continuously at 40 °C through 50 °C, it derates to 114 A at 70 °C, so the thermal curve is worth checking if your panel runs hot. The 220 kA breaking capacity at 240 V gives serious fault-current headroom for high-SCCR installations; at 415 V it still interrupts 154 kA, and at 690 V it holds 7.5 kA.
This 3-pole MCCB delivers 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The steep drop above 440 V is typical for a compact-frame MCCB — at 690 V the 7.5 kA rating still covers most motor-starting fault duties, but verify against your transformer's secondary fault current if you're on a 690 V line.
At 76.2 mm wide, 130 mm tall, and 70 mm deep, this MCCB fits standard panel-mount cutouts for 3-pole SENTRON breakers.
