The Siemens 3VA1132-6EF36-0KA0 is a 3-pole SENTRON molded case circuit breaker for line protection, rated 32 A continuous at 40 °C and carrying a 220 kA interrupting capacity at 240 V — that's the figure that governs fault clearance on a 240 V distribution bus.
The breaker measures 76.2 mm wide by 130 mm tall by 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling the gland plate. Depth of 70 mm leaves room for rear bus connections in a shallow cabinet. Power loss is 10.6 W maximum, so thermal rise inside a sealed enclosure is manageable; no forced ventilation required for a single unit in a typical panel.
Rated 32 A from 40 °C through 50 °C, then derates to 31 A at 55–60 °C and 30 A at 65–70 °C. That means in a hot panel — say near a drive or transformer — you lose 2 A off the nameplate.
