Siemens SENTRON 3VA1132-6EF36-0CH0 — 32 A MCCB for Line Protection
Breaking capacity is the headline spec here: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and still 17 kA at 690 V. The 690 V rating at 17 kA also makes it usable in 600 V class Canadian and some IEC industrial networks. The 76.2 mm width (3-pole) and 130 mm height fit the SENTRON 3VA family footprint, so it drops into existing SENTRON panel layouts without re-drilling.
Above that, it derates linearly: 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.
The undervoltage release (UVR) is built in; it will trip the breaker if control voltage drops below about 70% of rated. This is standard for applications where a loss of control power must open the main disconnect — emergency stops, safety circuits, or sequential start interlocks. The integrated auxiliary trip module is order code 3VA9608-0BB24, a separate line item if you need a spare.
