The interrupting ratings are substantial: 187 kA at 240 V AC, 121 kA at 415 V AC, 36 kA at 440 V AC, and 17 kA at 690 V AC, so it handles high-fault-current scenarios typical of industrial switchboards and transformer secondaries.
Temperature derating is flat from 40 °C to 50 °C at 200 A, then drops to 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C.
This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.
The interrupting rating is 121 kA at 415 V AC, which covers high-fault-current industrial distribution panels.
