At 415 V it still clears 75.6 kA — enough for most industrial main feeders. The 32 A rating holds flat from 40 °C to 50 °C, then drops only 1 A per 5 °C step: 31 A at 55 °C and 60 °C, 30 A at 65 °C and 70 °C (–). That's a shallow derating curve — useful when the MCCB sits in a warm enclosure alongside other heat sources. The 101.6 mm width is a standard 4-inch frame — fits common DIN-rail or panel-mount footprints without surprises.","metaTitle":"Siemens 3VA1132-4EE42-0AA0 SENTRON MCCB, 32 A, 4-Pole, 121 k","metaDescription":"Siemens 3VA1132-4EE42-0AA0 SENTRON molded case circuit breaker, 32 A rated, 4-pole, 121 kA breaking at 240 V.

The thermal element protects against sustained overloads, the magnetic element trips instantaneously on short-circuit.
