That TM210 designation means the thermal pickup is fixed at 100 A, and the magnetic short-circuit trip is set at 10x In — so it holds motor inrush without nuisance tripping but clears a bolted fault fast. Breaking capacity runs from 75.6 kA at 240 V down to 7.5 kA at 690 V, which covers most industrial distribution panels up to the 690 V tier.
Derating and thermal budget — the real-world current
At 55 °C it derates to 96 A, at 60 °C to 94 A, and at 70 °C to 90 A. That means in a warm panel — say 55 °C ambient — you lose 4 A of headroom. If your continuous load is 95 A at that temp, it holds; if you're pushing 98 A, you need to either ventilate the enclosure or step up to the next frame.
Auxiliary contacts and shunt trip — what's wired in
That shunt trip lets you remote-trip the breaker via a PLC or E-stop relay, which is standard for safety circuits or remote disconnect panels.
Panel fit — dimensions and IP
Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — standard 3-pole MCCB width for a 100 A frame.
