The adjustable short-circuit release (li max. 320 A) lets you dial in the magnetic trip for motor inrush or transformer magnetizing current, which keeps nuisance trips off your PM schedule. Out here in the grease, if a breaker can't handle the fault current at the transformer secondary, you're replacing more than the breaker — this one does. Rated continuous current Iu is 32 A, and the thermal derating curve holds that figure up to 50 °C ambient — at 55 °C it drops to 31 A, at 65 °C to 30 A. If your panel sits near a furnace line or a hot motor drive, that derating is the number to spec by, not the label ampacity. DC operation is rated up to 600 V, which matters if you're breaking a battery bank or DC bus. Inside a NEMA 1 or 12 enclosure that's fine; don't put it on the washdown side of a food line without a sealed cover. The N-conductor protection is rated at 100%, so the neutral pole is fully rated — no derating needed on 4-wire systems with harmonic loads.","metaTitle":"Siemens 3VA1132-3GD42-0AA0 SENTRON MCCB, 32 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1132-3GD42-0AA0 molded case circuit breaker, 32 A, 4-pole, 75.6 kA at 240 V.
