Interrupting ratings that define the bus
The 3VA1225-5EF32-0AG0: This 3-pole MCCB carries 187 kA at 240 V AC and 121 kA at 415 V AC — numbers that put it squarely in high-fault-duty territory for industrial switchboards.
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. The 70 mm depth × 105 mm width × 158 mm height footprint is standard for the 3VA frame; it mounts on a DIN rail or direct-panel, with IP40 protection on the front face.
Auxiliary contacts and release configuration
No undervoltage release, no shunt trip, no ground-fault module on this variant. The overcurrent release is the fixed TM240 thermal-magnetic type; there is no communication function, phase-failure detection, or voltage trigger. It is a straightforward line-protection breaker for applications where you just need basic overload and short-circuit protection with remote indication.
