It's a 3-pole unit rated 8 A at 40 °C (full rating holds through 50 °C; above that it derates 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 TM110M overcurrent release is a thermal-magnetic fixed-trip design — no field-adjustable trip unit, so the 8 A rating is the only setting. That's fine for a fixed motor load where the FLA is known; for variable loads you'd want an adjustable electronic release.
Short-circuit breaking capacity varies sharply with system voltage: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 7.5 kA at 690 V is the limiting figure — if your panel feeds a 690 V motor starter, the available fault current must stay under 7.5 kA, or you need a current-limiting upstream device. At 415 V the 121 kA rating covers virtually any industrial service entrance.
Dimensions: 130 mm height, 76.2 mm width (3 in), 70 mm depth (2.76 in).
Environment and lifecycle
The 70 °C operating ceiling matches the derating curve — at that temperature the breaker is still functional at 7.04 A. Lifecycle status is current — this is an active, in-production part.
