The switching capacity class N means it's built for standard industrial distribution, not high-fault petrochemical or utility tie points. This breaker delivers 76 kA at 240 V AC, 53 kA at 415 V AC, 32 kA at 440 V AC, and 11.9 kA at 500 V AC. The 76 kA at 240 V gives comfortable margin for most North American panelboards. ## Thermal derating — no surprise at the back of a warm panel Rated 32 A from 40 °C through 50 °C, then it starts to taper: 31 A at 55 °C and 60 °C, 30 A at 65 °C and 70 °C. If this breaker sits next to a transformer or drive in a sealed enclosure, you lose about 2 A at elevated temperatures — plan your load accordingly.","metaTitle":"Siemens 3VM1132-3EE46-0AA2 SENTRON MCCB, 32 A, 76 kA at 240","metaDescription":"Siemens SENTRON 3VM1132-3EE46-0AA2 molded case circuit breaker, 4-pole, 32 A, 76 kA at 240 V AC, 53 kA at 415 V AC.
