It's the line protection version, meaning its primary job is protecting cable and bus from overloads and short circuits in a distribution panel — not motor protection, not generator protection. The TM240 overcurrent release is a thermal-magnetic unit: the thermal element handles sustained overloads, the magnetic element clears high-current faults fast.
This MCCB carries a 121 kA breaking capacity at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. For a 415 V industrial panel, 75.6 kA SCCR gives you headroom above most transformer-fed bus ratings — you're not riding the edge of coordination.
Rated 25 A continuous at 40 °C, and it holds that rating flat through 50 °C. At 55 °C it derates to 24 A, at 60 °C to 23.5 A, at 65 °C to 23 A, and at 70 °C to 22.5 A.
Built-in accessories — what's on board
Also includes a shunt trip (STL) — a voltage-triggered release that lets a remote signal (E-stop, fire alarm, undervoltage relay) trip the breaker electrically. The integrated auxiliary trip is order code 3VA9688-0BL30.
The 15,000-cycle latching endurance (mechanical) is typical for this class — fine for distribution duty where it operates a few times a year, not for frequent switching.
