The TM240 thermal-magnetic trip unit gives a fixed thermal pickup of 32 A and a magnetic trip threshold of 240 A — the magnetic setting is 7.5x the rated current, so it handles motor inrush without nuisance trips on pump or compressor starts. The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into a SENTRON panelboard or a DIN-rail adapter without re-drilling. No communication module or ground-fault monitoring is fitted on this variant; it's a straight line-protection device with the UVR as the only auxiliary release.","metaTitle":"Siemens 3VA1132-4EF32-0DA0 SENTRON MCCB, 32A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1132-4EF32-0DA0 molded case circuit breaker. 32A rated current at 40°C, 3-pole, 121kA breaking capacity at 240V.
