It carries a continuous current rating of 500 A at 40 °C, and the thermal derating curve holds that full 500 A up through 50 °C ambient — only dropping to 495 A at 55 °C and 480 A at 70 °C, meaning it handles warm panel environments without a significant de-rate. Interrupting capacity is the headline here: 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 9 kA at 690 V. For a 500 A frame, that 121 kA at 415 V gives real selectivity headroom in high-fault industrial distribution — you can coordinate downstream without forcing a main breaker upgrade. The design is motor protection, so the thermal-magnetic curve is shaped for motor inrush and overload profiles.
The breaker measures 248 mm high by 138 mm wide by 110 mm deep. It mounts into a standard SENTRON panelboard or onto a mounting plate in an enclosure. The 3-pole form factor matches the common footprint for 500 A frame MCCBs — check your busbar centers and enclosure depth before committing the cutout. Maximum power loss is 99 W, which matters for thermal management inside a sealed enclosure — factor that into your ventilation or de-rate calculation if you are packing multiple breakers in one cabinet.
