Line protection MCCB with TM210 release
Breaking capacity is the headline spec here: 220 kA at 240 V AC, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. That puts this breaker well into high-fault-duty territory — suitable for main feeders or sub-distribution where SCCR requirements are stiff. The 3-pole form factor (76.2 mm wide, 130 mm tall, 70 mm deep) mounts on a DIN rail or direct-panel with standard busbar connections.
Above that, derating is gradual: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, and 91 A at 70 °C. Storage range is -40 to 80 °C, wider than the operating envelope. That matters for spares stored in unheated warehouses or shipped through cold climates. Maximum power loss is 25 W. In a dense panel with multiple breakers, that heat adds up — account for it in the enclosure thermal calculation.
