The ETU860 brings adjustable long-time (tr 0.5–25 s) and short-time (tsd up to 0.5 s) response values, plus ground-fault monitoring via summation current formation on the L-conductor. That makes it suitable for feeders where selective coordination and earth-leakage detection are required — common in process plant sub-distribution. Rated breaking capacity is 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.8 kA at 690 V. At 690 V the capacity drops sharply to 3.8 kA, so verify your system's prospective fault current at that voltage before specifying. Maximum power loss is 1.6 W — negligible for thermal budgeting inside a panel.","metaTitle":"Siemens 3VA2140-6KQ32-0AA0 SENTRON MCCB, 40 A, 3-Pole, ETU86","metaDescription":"Siemens 3VA2140-6KQ32-0AA0 SENTRON molded case circuit breaker, 40 A rated, 3-pole, ETU860 electronic trip unit, 242 kA at 240 V.

The deciding difference is the trip unit and accessory configuration — the 6KQ32 carries an ETU860 with ground-fault monitoring, while the 8JQ42 variant uses a different trip system. If the panel was wired for the 8JQ42's specific auxiliary connections and neutral-sensing arrangement, verify compatibility before swapping; the mounting hole pattern and main power terminals are identical."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2140-6KQ32-0AA0","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3VA2140-6KQ32-0AA0 when reusing this data.
