That's standard for motor feeders where the contactor and overload handle running protection and the MCCB is there for the hard fault. The 220 A rating at 65 °C means the trip unit is calibrated for continuous current at that ambient; in a 50 °C cement plant control room you have headroom, but if the panel sits near the kiln at 65 °C you're right at the limit. Breaking capacity varies with voltage: 100 kA at 240 V, 70 kA at 415 V, 65 kA at 440 V, down to 10 kA at 690 V. For a 415 V motor feeder that 70 kA Icu gives solid selectivity with upstream gear — you can coordinate without oversizing the whole lineup. The 3-pole, 3-protected-pole configuration (3D) means all three poles have trip protection, not just a switched neutral. IP40 enclosure protection keeps out tools and fingers but not dust — this is a panel-mounted breaker, not a standalone enclosure. Mount it on a backplate (flat, horizontal or vertical) inside a cabinet that handles the dust seal.","metaTitle":"Schneider Electric C25H3MA220 ComPacT NSX 250H, 220A MA Trip","metaDescription":"Schneider Electric C25H3MA220 ComPacT NSX250H MCCB. 220A MA magnetic trip unit, 70kA Icu at 415V AC.
