What this MCCB delivers
Its interrupting capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V — enough to clear high-fault conditions on a distribution bus without upstream coordination headaches. The 100 A rating holds flat from 40 °C to 50 °C, then derates gradually to 91 A at 70 °C, so a panel running at 45 °C gets the full 100 A.
Fit and panel integration
Footprint is 101.6 mm wide by 130 mm tall by 70 mm deep — a 4-pole MCCB that fits standard Siemens SENTRON mounting bases. Optional motor drive allows remote tripping or reset — useful for unattended switchgear.
The 100 A frame with TM220 release is sized for feeder or large branch circuits in commercial and industrial distribution. At 415 V it still interrupts 52.5 kA, so it handles most 400 V distribution bus faults.
