The Siemens SENTRON 3VA1032-3ED32-0AD0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, with a TM210 thermal-magnetic release and a rated continuous current Iu of 32 A. It carries a breaking capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, and 32 kA at 440 V — the 240 V figure is the one to size against for high-fault utility feeds or transformer secondaries in North American panels.
Ratings and thermal derating
The 32 A continuous rating holds flat from 40 °C through 50 °C ambient. Above that it derates stepwise: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If your panel internal ambient runs above 50 °C, the actual ampacity drops — size the breaker for the derated figure, not the nameplate 32 A. The TM210 release is a fixed thermal-magnetic type — no interchangeable trip units, no field-adjustable long-time pickup. The adjustable response value time tr max. is 1 s, which governs the short-time delay band for coordination with downstream breakers.
Physical fit and auxiliary contacts
Footprint is 76.2 mm wide by 130 mm tall by 70 mm deep — standard 3-pole MCCB spacing for a 4-inch (101.6 mm) DIN-rail or panel-mount cutout. The 70 mm depth is the dimension behind the panel face; check clearance to the enclosure door or bus bars. Comes with 3 auxiliary switches HQ (high-quantity) factory-installed. No undervoltage release, no shunt trip, no ground-fault monitoring, no communication module — this is a bare line-protection breaker with aux contacts for status feedback. The IP40 front protection means it's suitable for a dry indoor panel; not rated for washdown.
