The Siemens SENTRON 3VA1132-3EE32-0KF0 is a 3-pole molded case circuit breaker rated for line protection, carrying a continuous current of 32 A at 40 °C ambient — the figure that governs thermal sizing in a closed panel. Per the datasheet, the breaker holds that 32 A rating through 50 °C without derating; at 70 °C it still delivers 30 A. The interrupting capacity at 240 V AC is 75.6 kA, which means it can safely clear a fault up to that level without cascading upstream — a figure that matters for SCCR compliance on a distribution board. Rated insulation voltage is 800 V, so the breaker is suitable for 480/277 V and 600 V systems with margin.
The breaker measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a standard 3-pole MCCB footprint that drops into a SENTRON distribution panel or a DIN-rail adapter plate without re-drilling. Maximum power loss is 10.6 W, which is within the dissipation budget of a typical steel enclosure with natural convection; no forced cooling required at rated load.
