The Siemens SENTRON 3VA1032-4ED36-0KC0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying 32 A continuous current at 40 °C through 50 °C before the thermal curve begins to derate — 30.72 A at 55 °C, stepping down to 28.8 A at 70 °C. That derating profile means the breaker holds its full 32 A rating across typical panel ambient conditions; you only lose headroom above 50 °C, which is worth noting if the breaker sits near a heat source or in a crowded enclosure. The interrupting ratings climb steeply with voltage: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V. For a 415 V distribution board, that 75.6 kA SCCR gives solid selectivity headroom downstream of a larger upstream device — the spectrum doesn't lie when you're coordinating fault levels. The auxiliary contact version is 2 auxiliary switches HQ, and the integrated auxiliary trip is order code 3VA9688-0BL33.
The 3VA1032-4ED36-0KC0 measures 70 mm deep, 76.2 mm wide, and 130 mm high.
