MCCB for line protection — 200 A frame, TM220 release
The continuous current rating holds at 200 A from 40 °C through 50 °C, then derates linearly to 176 A at 70 °C. That means in a 50 °C panel ambient — common in enclosed switchgear — you still get the full 200 A; above that, the thermal curve governs the actual ampacity. The interrupting ratings are 76 kA at 240 V AC, 53 kA at 415 V AC, 32 kA at 440 V AC, and 12 kA at 500 V AC. For a 415 V distribution board, the 53 kA figure gives solid headroom against most utility fault levels. Maximum power loss is 42 W — relevant for thermal coordination inside a sealed enclosure. Front protection is IP40, so tools or fingers won't contact live parts, but the body is not sealed against moisture ingress.
Dimensions are 105 mm wide, 158 mm high, 70 mm deep.
