The SENTRON 3VM1132-3ED42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated 32 A at 40 °C, with a TM210 thermal-magnetic overcurrent release.
Interrupting capacity and thermal derating
Breaking capacity drops with system voltage: 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V. These are the symmetrical RMS values the breaker can safely interrupt under fault conditions without welding or arc propagation. The continuous current rating holds at 32 A from 40 °C through 50 °C, then steps down to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C.
The breaker occupies 101.6 mm width, 130 mm height, and 70 mm depth. The 4-pole footprint matches standard MCCB cutouts for 100 A frame sizes; verify the mounting hole pattern against the existing backplate if replacing a different brand.
