Breaking capacity reaches 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 6 kA at 690 V — figures that govern selectivity and SCCR coordination in a distribution panel. The 250 A rating holds steady through 50 °C, then derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C.
Maximum power loss is 48 W, which should be factored into enclosure thermal calculations.
187 kA at 415 V (also 187 kA at 440 V, 121 kA at 500 V, 6 kA at 690 V).
Submit an RFQ — the part is sourced to order through independent distribution, with current price and lead time confirmed at quote time.
No — this variant is without auxiliary release and without ground-fault monitoring.
