The Siemens SENTRON 3VA1132-5EF32-0BH0 is a 3-pole molded case circuit breaker (MCCB) rated for 32 A continuous current across the 40 °C to 50 °C ambient range, with only a 2 A derating at 70 °C. That means it holds its full rating in a warm enclosure — a real advantage when the panel is packed tight and airflow is limited. Its interrupting capacity is substantial: 187 kA at 240 V, 121 kA at 415 V, and 75.6 kA at 440 V. The factory-fit auxiliary switch pack includes 2 auxiliary switches plus a trip alarm switch (HQ), and an undervoltage release (UVR) is already installed. That saves field wiring time if your safety circuit demands a UVR.
Integration notes for the wireman
The 70 mm depth leaves clearance behind a 200 mm deep enclosure; the 76.2 mm width means three of these fit in a 230 mm wide backplate section.
