The overcurrent release is a TM240 thermal-magnetic type, adjustable response time tr max. 1 s, and the auxiliary contact version is 2 auxiliary switches HP. The 32 A continuous rating holds flat from 40 °C through 50 °C, then derates to 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C — so in a warm enclosure near the top of the operating range (−25 °C to 70 °C), you lose roughly 10 % of the ampacity.","metaTitle":"Siemens 3VA1132-5EF32-0AB0 SENTRON MCCB, 32 A, 187 kA at 240","metaDescription":"Siemens SENTRON 3VA1132-5EF32-0AB0 molded case circuit breaker, 3-pole, 32 A rated continuous current, 187 kA at 240 V.
