Insulation voltage is rated at 800 V, which covers the gap between the bus and the breaker body for standard panel builds. ## Breaking Capacity Across Voltages — SCCR Planning This breaker's interrupting capacity drops predictably as voltage rises: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V panel (common in North America) the 32 kA at 440 V is the closest published point — expect the actual SCCR to sit between the 440 V and 500 V figures. That's enough for most industrial distribution boards unless you're feeding a transformer secondary with a stiff utility. At 55 °C it drops to 31 A, at 65 °C to 30 A, and at 70 °C to 30 A. That's a shallow curve; you can pack this breaker into a warm enclosure without losing much capacity. Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — that's 3 inches wide, 5.12 inches tall, 2.76 inches deep. It's a standard 3-pole MCCB width for DIN-rail or panel-mount installation.","metaTitle":"Siemens 3VA1132-3EF36-0AE0 SENTRON MCCB, 32A, 75.6kA at 240V","metaDescription":"Siemens SENTRON 3VA1132-3EF36-0AE0 molded case circuit breaker, 32A rated at 40°C, 3-pole, 75.6kA breaking capacity at 240V.
