This MCCB delivers 121 kA interrupting capacity at 240 V, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. Those figures cover most industrial service-entrance and sub-distribution fault levels; the 690 V rating is useful for 600 V class Canadian or mining installations where the full kA is still needed. The 800 V rated insulation voltage (Ui) supports use in 690 V systems with margin, and the 100 A frame at 40 °C holds flat through 50 °C — no derating needed up to that point. Above 55 °C it steps down to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C.
Dimensions are 130 mm height, 101.6 mm width, and 70 mm depth — a compact 4-pole footprint that fits standard MCCB mounting plates in SENTRON distribution boards. The 27.5 W maximum power loss should be factored into enclosure thermal calculations, especially in sealed or high-ambient cabinets. No communication module or ground-fault monitoring is fitted on this variant; the UVR is the only auxiliary release.
