Its continuous current rating holds at 160 A from 40 °C through 50 °C, then derates to 150 A at 70 °C — a thermal curve that matters when the breaker shares a warm panel with other heat sources. The interrupting ratings span the common industrial voltages: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. These figures define the fault-clearing capability at the point of installation — critical for selectivity studies and SCCR compliance on a 480 V or 690 V distribution panel.
The 3-pole form factor fits standard MCCB panel cutouts; verify bus-bar spacing and lug centers against the existing panel layout before ordering.
