The Siemens SENTRON 3VA1132-4GF46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated 32 A continuous, designed for line protection in distribution panels. Its TM240 thermal-magnetic release provides overload and short-circuit protection without electronic trip adjustment — a fixed-curve choice suited to standard feeder or branch circuits where coordination studies are already set. Breaking capacity varies sharply with system voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 500 V or 690 V. On a 480 V panel the 52.5 kA figure is the one to coordinate against — that is the available fault current the breaker must interrupt without upstream support. Thermal derating is minimal up to 50 °C (still 32 A); at 70 °C it holds 30 A. Rated insulation voltage is 800 V, and the front face carries IP40 protection — fine for a dry indoor panel, not for washdown zones.
Dimensions: 130 mm height, 101.6 mm width, 70 mm depth. The 4-pole width (101.6 mm) is standard for a 4-pole MCCB on a DIN-rail or panel-mount footprint. Verify the gland plate cut-out matches before drilling — the 70 mm depth leaves room for rear busbar connections in a typical 200 mm deep enclosure. Power loss is 10.6 W maximum at rated load. In a sealed panel with multiple breakers, that heat adds up — account for it in the thermal budget if the ambient inside the enclosure exceeds 40 °C.
Compared to the 3VA1110-5ED32-0AA0 (also a 4-pole, 32 A MCCB), the 3VA1132-4GF46-0AA0 carries a TM240 release versus the 3VA1110's TM210. The TM240 has a higher magnetic trip threshold — 240 A vs 210 A — so it tolerates larger inrush without nuisance tripping on motor or transformer feeders. The physical footprint and pole count are identical; it drops into the same panel cut-out and busbar arrangement.
