It's built for main feeder or large branch protection in distribution panels, motor control centers, and industrial switchboards. The headline number here is the interrupting capacity: 220 kA at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V. Above that it starts to taper: 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, 144 A at 70 °C. The TM240 release is fixed, not adjustable, so the trip curve is set at the factory.
Panel fit and auxiliary hardware
The shunt trip lets a remote pushbutton, PLC, or safety relay force the breaker open — common for emergency-stop chains or undervoltage protection schemes. No undervoltage release, no ground-fault module, no communication board on this variant. The auxiliary trip module is order code 3VA9688-0BL32 if you need a spare.
