Rated 100 A continuous across the full 40 to 70 °C ambient range, it holds its full rating without derating up to 70 °C, which simplifies panel thermal budgeting. The adjustable thermal-magnetic trip unit covers 300 A minimum to 1 500 A maximum, giving you a wide window to match motor full-load amps or downstream feeder protection. Breaking capacity is the headline: 330 kA at 240 V, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
That 86 mm depth includes the shunt trip and auxiliary switches mounted internally — no extra projection beyond the standard 3VA2 frame. When planning gland-plate clearance, account for the 86 mm plus wire bending radius for the line and load lugs.
