The TM220 overcurrent release combines a thermal bimetal for overload and a magnetic coil for short-circuit — no electronic trip unit, no communication function, no undervoltage release. That keeps the part simple for standard feeder or branch protection where selectivity and coordination are set by the breaker's own time-current curve. This 3-pole MCCB delivers 187 kA at 240 V AC, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. The 187 kA at 240 V suits high-capacity 240/120 V split-phase or 240 V delta secondaries where upstream transformers can push large fault currents. ## Panel integration and environmental limits The breaker measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that mounts directly onto a DIN rail or panel-mount base. Front-side protection is IP40, meaning tools or fingers won't contact live parts from the front, but the enclosure must keep the sides and rear clear of dust and moisture.","metaTitle":"Siemens 3VA1132-5EE32-0AA0 SENTRON MCCB, 3-Pole, 32 A, 187 k","metaDescription":"Siemens 3VA1132-5EE32-0AA0 SENTRON molded case circuit breaker, 3-pole, 32 A, TM220 release, breaking capacity 187 kA at 240 V.
