It carries a 220 kA breaking capacity at 240 V, 154 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V — meaning it can safely interrupt fault currents at those levels across common industrial voltages without upstream coordination failure. The TM240 release is the part that decides the trip curve: thermal-magnetic, fixed at 160 A continuous, with magnetic pickup set by the TM240 designation. No trip indicator, no voltage trigger, no phase-failure detection — this is a straightforward line-protection breaker, not a multifunction power monitor.
At 70 mm deep, 76.2 mm wide, and 130 mm tall, this breaker fits the standard SENTRON 3VA panel footprint — same width as the rest of the 3VA line, so it rows neatly on a DIN rail or mounting plate without odd gaps. The continuous current is rated 160 A from 40 °C through 50 °C, then derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C. Rated insulation voltage is 800 V, and the operating temperature range is -25 °C to 70 °C, with storage from -40 °C to 80 °C.
