SENTRON 3VA1132-4GD46-0AA0 — 32 A MCCB with TM210 Release
Breaking capacity reaches 121 kA at 240 V AC, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — figures that govern selectivity coordination with downstream breakers. At 415 V, common in European industrial panels, the 75.6 kA SCCR handles most transformer-fed fault levels without cascading upstream. Above that, current capacity tapers to 30 A at 70 °C — relevant for tightly packed enclosures where internal temperature rise is a concern.
No successor or PCN/EOL notice has been announced for this order code. The SENTRON 3VA series is Siemens' current MCCB platform.
The breaker occupies 101.6 mm width, 130 mm height, and 70 mm depth — a 4-pole footprint that fits standard Siemens 3VA panel mounting. Maximum power loss is 10.6 W, which contributes to enclosure thermal calculations. The TM210 release is factory-set and non-adjustable for thermal pickup, simplifying specification but requiring correct sizing at the design stage.
