What this MCCB delivers in a hot, dusty panel
Above that it derates linearly: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, 213 A at 70 °C. In a control room that sits at 50 °C near the kiln, you get the full nameplate; if the enclosure is cooking at 65 °C, you still have 222 A available — no forced derating guesswork. That gives you separate signals for breaker position, fault trip, and electrical status — enough to feed a PLC input card without external relays.
Spring-cage terminals accept copper or aluminium conductors; strip length and torque values are on the nameplate. Maximum power loss is 50.5 W at full load. In a sealed enclosure that number drives internal temperature rise — account for it in the thermal design if the panel is tight.
