The 70 mm depth and 158 mm height keep the footprint manageable for a 200 A frame, though the 140 mm width across four poles means the panel cutout and busbar spacing need to accommodate the full pole count. This is a line-protection variant, meaning the TM240 release is set for cable and busbar protection rather than motor or generator duty. No undervoltage release, no auxiliary contacts, no ground-fault monitoring are fitted on this order code, so any of those functions would need an external module or a different variant.
Above that, the TM240 release begins to thermally track: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, and 176 A at 70 °C.
Front protection and mechanical endurance
No trip indicator is fitted, so fault events must be identified by the breaker position or a separate indication circuit.
