At 55 °C it derates to 30.72 A, at 60 °C to 30.08 A, at 65 °C to 29.44 A, and at 70 °C to 28.8 A. The integrated auxiliary trip is order code 3VA9608-0BB11. No communication function, no phase failure detection, no ground fault monitoring, no voltage trigger, and no trip indicator. If you need remote status beyond the two aux contacts, you'll add an external module or a separate monitoring relay. ## Panel fit and protection class The 3-pole design with line protection (no ground fault) means it's a straight feeder or branch breaker for resistive, motor, or mixed loads within the derated current envelope. Latching endurance is 15,000 operations.","metaTitle":"Siemens 3VA1132-5EF32-0BC0 SENTRON MCCB, 32 A, 187 kA at 240","metaDescription":"Siemens 3VA1132-5EF32-0BC0 SENTRON molded case circuit breaker, 3-pole, 32 A rated continuous current, 187 kA breaking capacity at 240 V.
