SENTRON 3VA1132-4GD46-0AA0 — 32 A MCCB with TM210 Release
The Siemens SENTRON 3VA1132-4GD46-0AA0 is a 4-pole molded case circuit breaker (MCCB) rated at 32 A, designed for line protection in distribution panels. Its TM210 thermal-magnetic release provides overload and short-circuit protection without undervoltage or ground-fault monitoring, keeping the unit straightforward for standard feeder applications. 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. Rated insulation voltage is 800 V, and the breaker carries a 32 A continuous rating without derating up to 50 °C ambient. Above that, current capacity tapers to 30 A at 70 °C — relevant for tightly packed enclosures where internal temperature rise is a concern.
Lifecycle and Sourcing
No successor or PCN/EOL notice has been announced for this order code. The SENTRON 3VA series is Siemens' current MCCB platform.
Integration and Mounting
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. Front-face protection class IP40 keeps dust out of the enclosure interior; the breaker is intended for indoor panel installation, not washdown environments. 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.
