Above 50 °C the current rating drops in steps — 156 A at 55 °C, 151 A at 60 °C, 147 A at 65 °C, and 142 A at 70 °C — so the thermal trip curve stays predictable in a warm cabinet. The interrupting capacity reaches 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, 17 kA at 500 V, and 11.9 kA at 690 V, which gives selectivity headroom for most distribution panels without cascading upstream.
Maximum power loss is 33 W. Compliance documentation (UL, IEC, RoHS, REACH) is available from the manufacturer on request.
