The Siemens SENTRON 3VA1032-2ED36-0DH0 is a 3-pole molded case circuit breaker (MCCB) rated for line protection, carrying a continuous current Iu of 32 A. Its TM210 thermal-magnetic release handles overload and short-circuit protection without a separate voltage trigger. The interrupting ratings climb to 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — so at 415 V it clears faults up to 32 kA, which covers most industrial distribution panels downstream of a transformer.
Thermal derating and panel fit
The 32 A rating holds flat from 40 °C through 50 °C ambient. Above that it derates linearly: 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 ambient runs at 60 °C, plan for 30 A continuous — not the full 32 A. The enclosure footprint is 76.2 mm wide by 130 mm tall by 70 mm deep, which fits a standard 3-pole MCCB slot on a DIN rail or panel-mount base. IP40 on the front means the breaker face is protected against tools and wires over 1 mm; the body itself is not sealed against washdown.
Auxiliary contacts and undervoltage release
This variant ships with an integrated undervoltage release (UVR) — the coil drops the breaker if control voltage falls below the dropout threshold, which is standard for emergency-stop or undervoltage protection schemes. The auxiliary contact block provides 2 auxiliary switches plus 1 trip alarm switch (HQ configuration), giving remote status of the main contacts and the tripped state. The trip indicator on the front confirms a fault trip visually. The auxiliary release order code for replacement is 3VA9608-0BB25.
