The ETU350 electronic trip unit handles the overcurrent protection curve — no phase failure detection, no communication module onboard. Breaking capacity steps down across voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 6 kA at 690 V. Full 250 A holds through 50 °C ambient. At 55 °C it derates to 241 A, at 60 °C to 232 A, at 65 °C to 222 A, and at 70 °C to 213 A. The 105 mm width is three-pole standard for this frame size — it fits a standard SENTRON mounting pattern, no adapter plate needed. Maximum power loss is 50.5 W. That heat has to leave the enclosure — factor it into your thermal budget, especially in a sealed stainless steel panel. ## What the ETU350 release does The ETU350 is an electronic trip unit with LSI protection — long-time, short-time, and instantaneous. The undervoltage release drops the breaker when control voltage falls below its dropout threshold, which is standard for emergency-stop chains or undervoltage protection schemes. Mechanical endurance is rated at 20,000 operations.","metaTitle":"Siemens 3VA2225-6HN32-0BC0 SENTRON MCCB, 250 A, 3-Pole, ETU3","metaDescription":"Siemens 3VA2225-6HN32-0BC0 SENTRON MCCB, 250 A rated continuous current, 3-pole, ETU350 release, UVR included. 242 kA at 240 V.

The -6HN32-0BC0 uses an ETU350 with UVR and two HQ aux switches; the -5HN42-0BB0 has a different release and aux count. They share the same 250 A continuous rating and 3-pole form factor, so a panel designed for the -5HN42-0BB0 will accept the -6HN32-0BC0 mechanically, but the protection curve and aux wiring differ — verify the trip settings and control voltage before swapping."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3VA2225-6HN32-0BC0","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/3VA2225-6HN32-0BC0 when reusing this data.
