The interrupting ratings are the headline: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and it still holds 7.5 kA at 500 V and 690 V. That kind of short-circuit capacity is for high-fault panels where a standard MCCB would weld its contacts.
Thermal derating and real-world ampacity
Rated 12.5 A at 40 °C, it holds that same 12.5 A at 45 °C and 50 °C — no derating needed up to 50 °C. At 55 °C it drops to 12.1 A, then 11.9 A at 60 °C, 11.5 A at 65 °C, and 11 A at 70 °C.
The case measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint. The depth is the key number for a shallow enclosure: 70 mm (2.76 in) means it clears most 80 mm backpan depths without a spacer. Width at 76.2 mm (3 in) matches the typical 3-pole cutout. IP40 on the front keeps dust out of the mechanism; the rest of the breaker is open to the panel air for heat shedding.
Release and adjustments
The TM110M release is a fixed thermal-magnetic — the magnetic trip (short-circuit) is set at 200 A, no adjustment range (li min and li max both 200 A). That means the instantaneous pickup is 16x the continuous rating, which is typical for a motor-protection curve. An optional motor drive (product extension) is available for remote operation.
