Thermal derating and panel integration
The breaker carries its full 200 A rating up to 50 °C ambient. Above that it derates linearly to 176 A at 70 °C — a real consideration if the breaker lives in a crowded, poorly ventilated enclosure. The 42 W maximum power loss at rated current adds to the enclosure heat load; factor that into the thermal budget if you're stacking multiple breakers. Dimensions are 105 mm wide, 158 mm high, 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount bases. The 70 mm depth leaves clearance for rear-connected busbars in a typical switchboard.
