The ETU350 is a programmable electronic trip unit, so you get adjustable long-time, short-time, and instantaneous pickup settings rather than fixed thermal-magnetic curves — useful when you need selectivity downstream. The 3VA2140-5HN46-0AA0 carries 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. That steep drop above 500 V is typical for a 40 A frame — at 690 V the arc extinction gets harder. For a 480 V panel (common in North America) you'd interpolate between the 440 V and 500 V figures; the 75.6 kA at 500 V still gives headroom for most service-entrance applications. ## Environmental and integration notes","metaTitle":"Siemens 3VA2140-5HN46-0AA0 SENTRON MCCB, 40 A, 4-Pole, ETU35","metaDescription":"Siemens 3VA2140-5HN46-0AA0 SENTRON molded case circuit breaker, 40 A continuous, 4-pole, ETU350 electronic trip unit.

The difference is the trip unit — the 3VA2140-5HN46-0AA0 uses an ETU350 electronic release, while the 3VA2040-8HN42-0AA0 may have a different release variant. Verify the trip curve settings match your coordination study."},{"question":"What compliance documentation is available for this MCCB?","answer":"As a Siemens SENTRON product, it carries CE marking for the European market and is designed to IEC 60947-2.
