It carries 8 A continuous at 40 °C and holds a 220 kA interrupting rating at 240 V, which drops to 154 kA at 415 V and 121 kA at 440 V. Above 500 V the short-circuit capacity falls to 7.5 kA, so this is a high-fault panelboard or motor control center breaker, not a 690 V distribution breaker.
The TM110M thermal-magnetic release is fixed at 8 A continuous (Iu) but the magnetic trip can be adjusted up to 128 A — that's a 16:1 range, which lets you tune the short-circuit pickup to match the inrush of a specific motor or transformer without swapping the breaker. The 800 V rated insulation voltage (Ui) and 690 V AC operating voltage confirm it's rated for 480/600 V class systems, but the 7.5 kA SCCR at 500 V and above means you need a current-limiting upstream device if the available fault current exceeds that. Thermal derating is published from 40 °C through 70 °C: the breaker holds its full 8 A up to 50 °C, then drops to 7.76 A at 55 °C, 7.6 A at 60 °C, 7.36 A at 65 °C, and 7.04 A at 70 °C.
The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a 3-pole MCCB footprint that fits standard 3-pole panelboard and MCC buckets. Optional motor drive allows remote trip or reset, but the base unit has no communication function and no phase-failure detection. Ground-fault monitoring is not built in.
