Rated 32 A continuous at 40 °C ambient, it holds that rating flat through 50 °C before starting a gentle derate: 31 A at 55 °C, 30 A at 70 °C. Breaking capacity is where this breaker earns its panel space: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and still 11.9 kA at 690 V. That's a common requirement for safety circuits where the load must drop if control power fails. Footprint is 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in). In a 480 V panel fed from a 150 kVA transformer, the available fault current at the main lug is typically 20–30 kA, so this breaker has 4x headroom. That matters for selective coordination: you can put a 32 A feeder breaker downstream of a larger main and trust the main won't trip on a downstream fault if the time-current curves are properly gapped.","metaTitle":"Siemens 3VA1132-4EF32-0BA0 SENTRON MCCB, 32A, 3-Pole, 121kA","metaDescription":"Siemens SENTRON 3VA1132-4EF32-0BA0 molded case circuit breaker, 32A rated, 3-pole, 121kA breaking at 240V.
