Its interrupting capacity reaches 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 8 kA at 500 V — figures that define its fault-clearing capability across common distribution voltages.
Continuous current capacity holds at 100 A from 40 °C through 50 °C, then steps down to 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Maximum power dissipation is 39 W. For a 4-pole breaker at this frame size, the thermal curve is the binding constraint in a sealed or high-ambient enclosure — plan the panel's internal temperature rise against the 50 °C threshold before derating begins.
Physical footprint and mounting
The 4-pole width of roughly 4 inches is standard for this class of MCCB, so it fits existing SENTRON panel cutouts and bus-bar centers without re-drilling. No communication function, trip indicator, or voltage trigger is built in — this is a straight thermal-magnetic protector with no auxiliary electronics.
