Motor protection MCCB with ETU550M — 40 A, 110 kA @ 415 V
The Siemens 3VA2140-7MP36-0AA0 is a 3-pole IEC frame 160 molded case circuit breaker rated 40 A continuous, with a 110 kA interrupting capacity at 415 V AC (breaking capacity class C). ETU550M electronic trip unit with LSI protection: long-time (Ir) adjustable 16 A to 40 A, short-time (Isd) 1.2 to 15× In, instantaneous (Ii) 3 to 15× In. Motor-protection curve shaping matches motor inrush and start profiles.
RoHS compliant since 01-01-17. Export control: AL N / ECCN 9N9999 — no special licensing required for most destinations.
Terminal connection type — lug or box terminals accept copper/aluminum conductors sized for 40 A continuous. The 3VA frame 160 footprint is consistent across the family; if you are swapping an older 3VF or 3VL breaker in the same enclosure, verify the mounting hole pattern and bus-bar centers against the existing backplate.
