MCCB with high interrupting capacity for line protection
It is configured for line protection — no undervoltage release, no ground fault monitoring, no auxiliary contacts, and no communication module. The interrupting ratings are the headline: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V.
At 55 °C it drops to 48 A, at 60 °C to 47 A, at 65 °C to 46 A, and at 70 °C to 45 A.
Front protection is IP40 — sealed against tools and small wires, not washdown. No auxiliary contact version is fitted, and there is no N-conductor protection. For DC network applications, the 3VA molded case circuit breaker device manual covers the specifics.
