What this MCCB delivers for the panel
The Siemens SENTRON 3VA1132-3EF36-0HC0 is a 3-pole molded case circuit breaker rated 32 A at 40 °C, sized for line-protection duty in distribution panels. Its breaking capacity hits 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V — enough headroom for high-fault utility feeds or transformer secondaries. The 70 mm depth and 76.2 mm width fit standard MCCB mounting footprints, so it swaps into existing SENTRON-based panels without re-drilling the backplate.
Ratings that matter for the BOM line
Rated current holds at 32 A from 40 °C through 50 °C, then derates to 30 A at 70 °C — useful if the breaker sits in a warm enclosure near other heat sources. Insulation voltage is rated 800 V, so it handles 480 V and 600 V class systems with margin. Maximum power loss is 10.6 W, which keeps the internal temperature rise manageable in a crowded panel. The shunt trip (STL) and two HQ auxiliary switches are built in, so you don't need separate add-on modules for remote trip or status feedback.
