Three poles, 25 A continuous rating at 40 °C, and an ETU350 electronic trip unit that gives you adjustable overload and short-circuit protection curves. The interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V, and still holds 75.6 kA at 500 V — enough headroom for most industrial service entrances or feeder circuits without cascading upstream breakers.
Sizing and environment
Rated current holds flat at 25 A all the way from 40 °C to 70 °C ambient — no derating curve to chase in a warm enclosure. Storage range is -40 °C to 80 °C, operating range -25 °C to 70 °C. Dimensions are 181 mm high, 105 mm wide, 86 mm deep — standard MCCB footprint for a 3-pole frame in this class.
