Siemens SENTRON 3VA1032-2ED36-0JA0 — 32 A MCCB with Shunt Trip
The Siemens SENTRON 3VA1032-2ED36-0JA0 is a 3-pole molded case circuit breaker (MCCB) rated 32 A continuous at 40 °C, designed for line protection in distribution panels. It carries a TM210 thermal-magnetic overcurrent release — the thermal element handles overloads, the magnetic element clears short circuits. A built-in shunt trip (STL) allows remote tripping via a control voltage, useful for emergency-stop circuits or interlocking schemes. Breaking capacity varies with line voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. That 52.5 kA at 240 V gives solid headroom for high-fault panels on North American 240/120 V services. At 690 V the 7.5 kA figure still covers most industrial motor-control centers, but verify against your transformer's nameplate impedance and the available fault current study. Rated insulation voltage is 800 V, so the breaker is safe for 690 VAC systems with margin. The 32 A rating holds from 40 °C up to 50 °C; at 55 °C it derates to 31 A, and at 70 °C it's 30 A. That derating curve matters if the breaker sits in a crowded, warm enclosure — don't load it past 30 A if ambient hits 65 °C.
Mounting and Integration
Dimensions: 130 mm high, 76.2 mm wide, 70 mm deep. That 70 mm depth is the key fit dimension for shallow enclosures — measure your gland-plate clearance before committing the BOM. The 76.2 mm width (3 inches) matches the standard 3-pole MCCB footprint on a DIN rail or panel-mount adapter. No communication function on this variant; it's a standalone thermal-magnetic breaker with a shunt trip for remote control.
