It carries a 25 A continuous rating at 40 °C ambient, holds that rating through 50 °C, then derates to 23 A at 70 °C — so the thermal curve stays flat across typical panel ambient, and you only lose headroom above 55 °C.
Interrupting capacity and voltage ratings
Interrupting capacity is 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V.
Three-pole, 76.2 mm wide, 130 mm tall, 70 mm deep — that's a standard 3-inch wide footprint for a 3-pole MCCB in this class. Max power loss is 8.5 W, so thermal rise inside a crowded enclosure is manageable — no forced cooling needed for the breaker itself.
