It carries an ETU350M electronic overcurrent release with adjustable trip classes 10A, 10E, and 20E, letting you match the trip curve to the thermal characteristics of the motor load — 10A for standard motors, 20E for high-inertia starts like fans or centrifuges. Three-pole construction handles three-phase motor circuits, and the built-in phase failure detection provides an additional layer of protection against single-phasing — a common failure mode that cooks motor windings.
At 440 kA, it can interrupt a bolted fault on a large transformer secondary without cascading upstream, provided the upstream device is coordinated.
Front-face protection class is IP40. If you need shunt trip, UVR, or Modbus, you're looking at a different variant in the 3VA2 family.
Maximum power loss is 0.5 W — negligible for panel thermal budgeting. As a Siemens SENTRON product, this MCCB carries the usual compliance documentation (UL, IEC, CSA, CE, RoHS, REACH) — available on request with the RFQ.
