Rated insulation voltage is 800 V, and the interrupting capacity reaches 330 kA at 240 V, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V. The 4-pole construction with an ETU320 electronic overcurrent release provides adjustable protection for feeder and main circuits.
It mounts into a standard panel or enclosure footprint for SENTRON 3VA breakers. Front-side IP40 protection covers the operator interface; the device has no trip indicator, undervoltage release, or communication function.
The 100 A continuous rating at 70 °C ambient means this breaker delivers its full rated current even in a hot enclosure — no thermal derating curve to apply. The ETU320 release allows adjustment of the long-time, short-time, and instantaneous pickup, giving selectivity flexibility in multi-level distribution.
