It carries an ETU350 electronic trip unit, adjustable for long-time (Ir) up to 800 A and instantaneous (Ii) up to 8000 A, giving you granular coordination with downstream feeders. Breaking capacity reaches 187 kA at 240 V, 121 kA at 415 V, and 53 kA at 690 V — figures that tell you it handles high-fault utility feeds without cascading upstream.
The 800 A rating holds flat through 60 °C ambient; at 65 °C it derates to 767 A, and at 70 °C to 703 A.
Dimensions are 320 mm high, 210 mm wide, 120 mm deep. The 120 mm depth is the key number for enclosure depth clearance — standard 400 mm deep panels clear it easily, but shallow backboxes (under 150 mm) may not. Front protection is IP40, so it's suited for indoor switchgear; no washdown rating.
