SENTRON 3VM1132-3GE42-0AA0 — 4-pole MCCB, 32 A, 76 kA at 240 V
The Siemens SENTRON 3VM1132-3GE42-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated 32 A at 40 °C with a TM220 thermal-magnetic overcurrent release, designed for line protection in distribution panels. Its interrupting capacity reaches 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 12 kA at 500 V — covering most industrial low-voltage fault levels. The 70 mm depth and 101.6 mm width fit standard MCCB mounting footprints; IP40 on the front suits enclosed panel installation.
Thermal derating and continuous current
Rated current 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 TM220 release handles minimum loads down to 1 A, so it can protect lightly loaded branch circuits without nuisance tripping.
Integration notes
Four-pole design with 100% N-conductor protection. Insulation voltage rated 800 V. Power loss 11 W maximum. Ground-fault monitoring version is without. Mounts in standard panel cutouts for SENTRON 3VM frame breakers; verify busbar and lug kit compatibility with the specific distribution board.
