The 32 A rating holds from 40 °C through 50 °C ambient; above that it derates linearly 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. ## Auxiliary and undervoltage release configuration The integrated auxiliary trip module is order code 3VA9608-0BB25 — if you need a spare or replacement, that's the mate. No voltage trip, no communication function, no phase-failure detection, and no ground-fault monitoring on this version — it's a straight line-protection breaker with undervoltage release. Dimensions are 76.2 mm wide, 130 mm tall, 70 mm deep — standard 3-pole MCCB footprint for a 32 A frame. No trip indicator on the front; status is read through the auxiliary switch contacts.","metaTitle":"Siemens 3VA1132-5EF32-0DC0 SENTRON MCCB, 32 A, 3-Pole, 187 k","metaDescription":"Siemens 3VA1132-5EF32-0DC0 SENTRON molded case circuit breaker, 32 A rated, 3-pole, TM240 release, 187 kA breaking at 240 V.
