Its TM240 thermal-magnetic overcurrent release handles the overload and short-circuit trip curve. The interrupting ratings climb to 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — so at the common 415 V distribution level it clears faults up to 121 kA without cascading upstream.
Current derating and thermal limits
Above that it derates: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C.
Auxiliary and undervoltage release
The integrated auxiliary trip order code is 3VA9608-0BB25. The latching endurance is rated at 15,000 operations.
The 3-pole footprint matches standard SENTRON 3VA panel cutouts; verify gland-plate clearance for the 70 mm depth if the enclosure is shallow.
