The TM210 thermal-magnetic release handles overloads and short-circuits; no undervoltage release or trip indicator is fitted, so this is a straight thermal-magnetic breaker for standard feeder or branch protection.
Rated breaking capacity is 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. That is a high-interrupting-capacity (HIC) frame — it clears faults well above typical utility transformer ratings at the lower voltages, so it is suited for main or sub-main distribution where high available fault current is expected.
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a 3-pole MCCB footprint that fits standard panel mounting.
