The interrupting capacity hits 330 kA at 240 V, 242 kA at 415 V, and still delivers 187 kA at 500 V, dropping to 3 kA at 690 V. The ETU330 electronic trip unit handles the overcurrent protection curve. This is the line-protection version (not motor-protection), so the trip characteristics are set for cable and busbar protection rather than motor inrush. The ground-fault monitoring uses summation current formation on the L-conductor — it sums the phase currents and trips if the vector sum exceeds the threshold, which catches arcing faults to ground without needing a separate neutral CT. The 105 mm width occupies three 35 mm DIN modules. The breaker accepts optional motor drive (: Yes), so remote tripping or re-closing can be added without changing the frame. No undervoltage release (: No) and no communication function (: No) on this variant — those are separate order codes if needed.","metaTitle":"Siemens 3VA2025-7HM36-0AA0 SENTRON MCCB, 25 A, 330 kA at 240","metaDescription":"Siemens SENTRON 3VA2025-7HM36-0AA0 molded case circuit breaker, 25 A continuous, 330 kA interrupting at 240 V.
