Breaking capacity reaches 220 kA at 240 V AC, 154 kA at 415 V, and 121 kA at 440 V — figures that cover most industrial fault-current scenarios without needing a current-limiting upstream device.
Where it fits — panel and footprint
The MCCB measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard SENTRON 3VA footprint that drops into existing panel layouts without re-drilling.
The 220 kA breaking capacity at 240 V is the headline number, but the more relevant figure for a 480 V panel is the 154 kA at 415 V (the closest standard voltage in the evidence). The TM240 thermal-magnetic release has a thermal element fixed at 50 A and magnetic pickup set to 240 A. No ground-fault monitoring or communication function is included on this variant. If you need those, look at the 3VA2 series with electronic releases or the 3VA1 with GFI module.
