The TM-D trip gives you L (thermal overload) and I (magnetic short-circuit) protection in one block; no separate earth-leakage module here, so if you need ground-fault detection you add a Vigi add-on downstream. The breaking capacity is the headline number: 85 kA Icu at 240 V AC, 36 kA at 415 V AC, and 35 kA at 440 V AC, all per IEC 60947-2. Mounting is on a backplate, not a DIN rail — this is a bolted-down frame breaker, sized for distribution panels where the bus bars run behind it. The front-face connections (both upside and downside) mean you land cables on the front terminals, not the back. IP40 enclosure protection keeps dust out but not water; IK07 impact resistance handles accidental tool drops.
What the durability numbers tell a panel builder
Electrical durability is 20,000 cycles at 440 V at half rated current (In/2), and 10,000 cycles at full rated current (In) at 440 V. At 690 V it drops to 5,000 cycles at In/2 and 2,500 at In. For a distribution breaker that sees maybe a few operations a year, these numbers are fine. If this were a motor-switching breaker seeing daily starts, you'd want a higher-cycle-rated device. The utilisation category A confirms it's designed for distribution, not direct motor starting under load.
