Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 500 V, and 9 kA at 690 V. At 415/440 V the 121 kA covers high-capacity industrial feeds. Thermal derating is published: full 500 A up to 50 °C, then 477 A at 55 °C, 455 A at 60 °C, 432 A at 65 °C, and 410 A at 70 °C.
Dimensions are 110 mm deep, 138 mm wide, 248 mm high — fits standard MCCB panel cutouts and bus-bar centers for a 3-pole 500 A frame. Maximum power loss is 99 W — account for that in enclosure thermal calculations.
