Its interrupting capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — numbers that tell you this breaker is built for high-fault-current panels where upstream coordination demands serious SCCR headroom. At 690 V it still clears 17 kA, which is useful for industrial drives fed from a 690 V distribution bus.
The 25 A rating holds flat from 40 °C through 50 °C, then derates to 24 A at 55 °C, 23.5 A at 60 °C, 23 A at 65 °C, and 22.5 A at 70 °C. That's a shallow derate curve — you can run this breaker near its nameplate in a warm enclosure without losing much headroom.
Built-in undervoltage release
No separate UVR module to buy and mount.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that fits SENTRON distribution panels and most DIN-rail-mount enclosures.
