Three poles, with an ETU340 electronic overcurrent release. Insulation voltage rated at 800 V, so it handles 480/600 V class systems with headroom. Breaking capacity is substantial for a 25 A frame: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V. That puts it in the high-interrupting category — suitable for transformer secondary or large bus feeds where fault current is high.
242 kA at 240 V, with 187 kA at 415/440 V, 121 kA at 500 V, and 3.7 kA at 690 V.
