It carries a continuous current rating of 200 A at 40 °C, and holds that full rating through 50 °C — above that it derates linearly to 176 A at 70 °C, so in a hot enclosure you size for the ambient, not the nameplate. The TM240 thermal-magnetic release provides fixed thermal protection for overloads and magnetic pickup for short-circuits — no electronic adjustments, which means it's a fit-and-forget part once the continuous current matches your load. Breaking capacity is the headline: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V. The 70 mm depth, 140 mm width, and 158 mm height fit standard SENTRON 3VA panel footprints.
Mounts in a standard distribution panel on a mounting plate or DIN-rail adapter (the 3VA range uses a common backplate pattern). The 4-pole form factor means it occupies the same width as four single-pole breakers in a row — plan your gland plate and busbar takeoff accordingly. No undervoltage release, no shunt trip, no communication function on this variant — it's a straight thermal-magnetic protector with no auxiliary electronics to wire.
