It's built for starter protection duty — meaning it's sized to sit ahead of a motor starter combination, handling both overload and short-circuit fault clearing in one package. The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and still delivers 75.6 kA at 440 V, so it's comfortable on high-fault industrial distribution panels where the available short-circuit current is substantial.
At 55 °C it derates to 194 A, at 60 °C to 188 A, at 65 °C to 182 A, and at 70 °C to 176 A. The maximum power loss is 42 W, which matters for internal enclosure heat rise calculations.
Physical fit and internal build
Dimensions are 105 mm wide, 158 mm high, 70 mm deep. That's a 4.13 x 6.22 x 2.76 inch footprint — standard for a 200 A frame MCCB. Inside, the basic switch is a 3VA12205MH320AA0, and the auxiliary switch configuration is three HQ-style aux switches.
