The headline number is the interrupting capacity: 187 kA at 240 V AC, dropping to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 / 690 V. At 55 °C it drops to 31 A, at 65 °C to 30 A, and it's still carrying 30 A at 70 °C. That's a shallow derating curve, meaning the breaker runs cool enough to keep its full rating through most industrial enclosure temperatures. If your panel is in a hot attic or near a furnace, you lose 1–2 A, not 5–10. The 3VA1132-5EF42-0AA0 measures 70 mm deep, 101.6 mm wide, 130 mm high — a standard 4-pole MCCB footprint for DIN-rail or screw-mount panel integration. The 4-pole design (three phases plus neutral) suits three-phase line protection where the neutral needs to be switched and protected.","metaTitle":"Siemens 3VA1132-5EF42-0AA0 SENTRON MCCB, 32 A, 4-Pole, 187 k","metaDescription":"Siemens SENTRON 3VA1132-5EF42-0AA0 molded case circuit breaker, 32 A rated at 40 °C, 4 poles, 187 kA breaking at 240 V.
