The Siemens SENTRON 3VA1132-3EF32-0DC0 is a 3-pole molded case circuit breaker rated for a continuous current of 32 A at 40 °C, with a thermal-magnetic TM240 overcurrent release. The rated insulation voltage Ui is 800 V, and the interrupting capacity reaches 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. The frame width is 76.2 mm, depth 70 mm, height 130 mm — a standard SENTRON 3VA fixed-mount footprint that drops into a DIN-rail or screw-mounted panel assembly.
Auxiliary and undervoltage release configuration
No communication module or ground-fault monitoring is fitted to this variant; those are available as separate add-on accessories in the 3VA platform.
Thermal derating across ambient temperature
Above that, derating begins: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C. If the panel internal ambient runs at 60 °C — common in a packed enclosure with multiple breakers — the effective continuous current drops to 30.08 A. That is the number to use for the load calculation, not the und derated 32 A.
