It carries a 200 A continuous rating at 40 °C ambient, holds that same rating through 50 °C, then derates to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C — so the thermal headroom is solid for a 200 A bus in a ventilated enclosure but needs a derating check if the panel runs hot. The interrupting ratings are what you size the SCCR plan around: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. Max power loss is 42 W.
Dimensions are 105 mm wide, 158 mm high, 70 mm deep. Width is 105 mm. The breaker ships with three HQ auxiliary switches built in.
