Rated insulation voltage is 800 V, and the interrupting ratings are 440 kA at 415 V AC and 187 kA at 690 V AC — headroom that keeps this breaker selective with downstream devices even under high fault current.
The front face carries an IP40 rating — protected against tools and small wires, but not washdown.
Rated continuous current 25 A, 3-pole, ETU320 electronic trip unit. Breaking capacity 440 kA at 415 V AC and 187 kA at 690 V AC. Rated insulation voltage 800 V. No derating required from 40 °C to 70 °C ambient.
