That means in a warm panel — say a 50 °C enclosure — you still get full 32 A continuous, but above that the thermal curve governs. The interrupting capacity drops with system voltage: 52.5 kA at 440 V, 11.9 kA at 500 V and 690 V. For a 480 V distribution board, the 11.9 kA figure is the one that determines SCCR compliance. The adjustable short-circuit release (li) maxes at 320 A, giving selectivity headroom downstream. That keeps the part simple and reliable for standard line protection, but if you need ground-fault monitoring or N-conductor protection, this variant omits both. ## Deployment context The dimensions are 70 mm depth, 101.6 mm width, 130 mm height — fits the common 4-pole MCCB cutout. An optional motor drive (product extension available) allows remote tripping or reset in automated lines.","metaTitle":"Siemens 3VA1132-4ED42-0AA0 SENTRON MCCB, 4P, 32 A, 121 kA","metaDescription":"Siemens 3VA1132-4ED42-0AA0 SENTRON molded case circuit breaker, 4-pole, 32 A rated current, 121 kA at 240 V.
