The TM210 overcurrent release handles thermal-magnetic trip for overload and short-circuit. A built-in shunt trip (STL) allows remote opening via a control signal — useful for emergency-stop or supervisory shutdown circuits. ## Ratings and ambient derating Rated current holds at 32 A from 40 °C through 50 °C, then steps down: 31 A at 55 °C, 30 A at 70 °C. That is a gentle derating curve — the breaker stays near its nameplate rating even in a warm enclosure. At 415 V the breaking capacity is 75.6 kA, still well above typical industrial service-entrance levels. Insulation voltage rated 500 V. Dimensions: 70 mm deep, 50.8 mm wide, 130 mm tall. The 50.8 mm (2 in) width fits common DIN-rail or panel-mount bases.","metaTitle":"Siemens 3VA1132-4ED22-0KA0 SENTRON MCCB, 2-Pole, 32 A, 121 k","metaDescription":"Siemens SENTRON 3VA1132-4ED22-0KA0 molded case circuit breaker, 2-pole, 32 A rated at 40 °C, 121 kA breaking capacity at 240 V.
