MCCB with ETU330 — interrupting capacity and thermal flatness
Its interrupting capacity reaches 440 kA at 240 VAC, 330 kA at 415 VAC and 440 VAC, 220 kA at 500 VAC, and 52.5 kA at 690 VAC — which means it can clear fault currents across a wide voltage range without cascading upstream breakers, a key advantage for high-fault panels close to the transformer. That simplifies panel design — the breaker delivers its full ampacity across the typical industrial ambient span.
No undervoltage release or communication module is fitted on this variant.
