MCCB for line protection, 125 A, 3-pole
It is configured for line protection — no voltage trip, no phase failure detection, no communication module. The interrupting ratings are substantial: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. That SCCR headroom means it can be placed upstream of most distribution panels without worrying about cascading failure under a high-fault bolted short. The TM210 release is the thermal-magnetic type — no electronic adjustment, so it's a fixed-trip curve suited for straightforward feeder or motor branch protection where you don't need programmable settings.
Rated continuous current holds at 125 A from 40 °C up to 50 °C, then derates to 120 A at 55 °C, 117.5 A at 60 °C, 115 A at 65 °C, and 112.5 A at 70 °C. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — fits standard 3-pole MCCB panel cutouts.
